you fool me once shame on you — and mom never repeated the trick

you fool me once shame on you, mom said on a sunday call, and the proverb arrived intact through a phone speaker that has, on its own merits, no business carrying that much grammar. she has, on record, never been fooled twice in her life. the milk anecdote is the smallest example. i wrote the line down with the hand that wasn’t holding the phone. the receipt wallet absorbed it quietly. mike, later at the corner, did not need the context to agree.

11:23am at the workstation. carla is in the all-hands training session two floors above, the one with the projector that hums and the trainer who has slides about empathy. nobody is checking on me until 12.

so. you fool me once shame on you. the version with the you at the front. most people drop the pronoun. most people say “fool me once shame on you” and march on. mom does not drop the pronoun. mom puts it back in. the truncated version, the one without the second-person opener, is the one that lives in dictionaries. the version with the you stuck on the front is the one that lives in mom’s kitchen, on a sunday, said into a landline, addressed to a specific human being who is, in her view, on warning.

you fool me once shame on you is the second-person opening of an old english proverb. the leading you turns the line into direct address — a finger pointed at a real person, not an abstract trickster. it survives mostly in family kitchens and bar conversations, where editors are not present to trim the pronoun off the front.

YOU. THAT YOU. THE ONE BEING ADDRESSED.

that is the part that ruined my morning, in the best way. the proverb, with the you in front, is no longer a saying. it is a sentence aimed at one specific person, in a specific room, who has done a specific thing. the abstract version — fool me once, shame on you — is a fortune cookie. the second-person version is a receipt. the difference is the subject of the longer essay i wrote on the noble tradition of being called this word, but on a sunday, between mom and a carton of milk, it became operational.

you fool me once, the second-person version

english is, in most of its proverbs, allergic to direct address. proverbs prefer the floating subject. a stitch in time saves nine. who’s stitching? unclear. a watched pot never boils. whose pot? not specified. the proverb does its work from a polite distance, the way a sign in an office tells everyone in general to clean the microwave and no one in particular ever does.

“you fool me once shame on you” rejects that politeness. it picks somebody. it leans across the table. it points. the you is the entire move. without it, the saying is a piece of advice. with it, the saying is a charge.

i had not noticed this for thirty-something years. mom said the long version on the phone at, by the clock above the microwave (the seventh, may it rest), 9:14am on a sunday, and the you sat there in the line like a witness. i felt, briefly, like a defendant. the milk had not even been mine. but the you doesn’t care whose milk. the you just wants somebody to look at.

this is the gift of the second-person variant. it forces the proverb to mean something. abstract proverbs are wallpaper. specific ones are court documents. on a sunday morning, with a coffee that is achievement and a phone speaker that is fine, mom turned wallpaper into a court document with one extra word.

why the second-person hits harder

the second-person version is rare in print because writers, by job description, like distance. the editor at any reasonable publication trims the leading you for the same reason editors trim leading wells and sos. the you looks redundant. the you looks colloquial. the you looks, to an editor with a pencil, like a word that didn’t make it past sunday school.

the editor is wrong. the you is the load-bearing word in the sentence. drop the you and the proverb is general. keep it and the proverb is aimed.

i learned this on a sunday. i had been quoting the short version of the saying in my head for years, applying it to waiters and dental insurance and the bulk place membership, all of which had fooled me more than once and none of which i had ever, in fact, addressed. the short version permits avoidance. you can think it without saying it. you can shame on you in your head about a human being you have never confronted in your life. that is the editorial benefit of dropping the you. it makes the proverb safe to think and unnecessary to say.

mom keeps the you because mom does not deal in unnecessary. mom deals in the kind of corrective conversation that the man who is loudly confident about his own intelligence usually needs and rarely receives. dunning would have benefited. kruger too. half the men in any office, frankly, would benefit from somebody saying you at the start of that sentence and meaning it.

mom said it on sunday, briefly, about the milk

here is the scene, for the record. mom called on sunday morning. mom always calls on sunday. (she dials at 9:07. she lets it ring four times. she hangs up before voicemail. then she calls again, the way she’s done since approximately 2014, on the theory that the second call is the real one. mothers know. it’s their power. it cannot be defeated.) the second call landed at 9:09. i picked up.

she had, the previous saturday, been at her own supermarket. she had, in her own words, “fallen for it again”. the it was a discount sticker on a half-gallon of milk that turned out, on inspection, to be near the expiration date. she had been there before. she had bought milk on a discount sticker before, in march, the same brand, the same trick, the same expiration arithmetic. the march milk turned, two days later, in her fridge.

“you fool me once shame on you,” she said into the phone. “you fool me twice, mister, that’s a different category.” she did not say “that’s shame on me”. she rejected the second clause. she replaced it with that’s a different category, which is, by my count, the only proverb upgrade i have heard in fifteen years. the original second clause assumes the second betrayal is the embarrassing one. mom’s revision treats the second betrayal as a categorical event. the second offense, in mom’s system, removes the offender from the negotiable category and places them in the non-negotiable one. that is a more useful proverb. that is, technically, a class of proverbs i have not seen elsewhere.

she did not buy the milk. she walked away from the discount sticker. she has, on record, never been fooled twice. mom is the person the proverb was written about, except mom is also the editor of the proverb, which is the only reason it survives the test.

mike at the corner heard a version of this, agreed

i went to the corner on monday. mike was at his end of the bar, near the napkin dispenser, working on a beer that had, by every visible sign, been there for ninety minutes. mike has a system for taxes. has not filed since 2019. the system is, on his own description, “self-regulating”. i told him about the second-person version of the proverb. i told him mom had upgraded the second clause. i told him about the milk.

mike is not, on most subjects, a fast endorser. mike makes you wait. mike has a glass at his elbow that needs supervision. but mike, on this one, took about a second.

“the you is the whole thing,” mike said. “without the you, you’re just complaining.” he tapped the bar twice with the bottom of the glass, which is mike’s way of marking a thought he intends to come back to. mike does not come back to thoughts. but he marks them, in case.

mike nodded through the pulpit. mike does not actually listen during pulpits. mike waits for the pulpit to end and then says one thing that proves he heard the whole thing. when i finished, mike said, “the milk lady is right about more than milk”, which is mike’s stamp of approval.

the receipt i kept just in case it happens a third time

i wrote the proverb down on the back of a receipt. the receipt was from a saturday earlier in the month. the receipt now lives in the receipt wallet, which is a small leather thing i carry, from 2019, half-broken, that holds receipts in chronological order. the proverb is on the back of a receipt for a tube of toothpaste, dated three weeks ago, in handwriting that is, frankly, not improving with age.

i did this because i did not want to lose it. the second-person version, with mom’s edit on the back half, has not been written down anywhere i could find. (i looked. briefly. on a website that knows things about proverbs. the website had the short version. the website did not have mom’s version. the website does not, on inspection, know what it doesn’t know.) if the proverb is going to survive in print, somebody had to put it on a piece of paper, and on monday afternoon that somebody was me.

the receipt wallet, in the bigger picture, is a hedge against the kind of forgetting that turns proverbs into wallpaper. i keep receipts because i don’t trust my memory, but i also keep receipts because some receipts are about the transaction, and some receipts are about the conversation. the milk receipt, in mom’s case, was both. she didn’t keep it. she kept the line instead. that is, on inspection, a more elegant filing system than mine.

this also connects, faintly, to the hot take about how the taxman sends letters in serif font, which is HT28 in my running list. the connection is that anything serious in english arrives with formatting cues. the taxman uses serif. mom uses the second-person pronoun. they are both, in their respective domains, telling you to take it seriously. ignore at your own filing-cabinet peril.

verdict, you fool me once shame on you is the version that holds up

so here is where i land. the version of the proverb that survives is the one with the you at the front. the editor’s version, the textbook version, the dictionary version — those are the wallpaper. the kitchen version is the operational one. the kitchen version, plus mom’s edit on the back half, is the one that actually predicts behavior in a milk aisle on a saturday.

the you is the whole sentence. the you is the difference between a saying you mutter into your coffee and a sentence you can address to a human being who has, by their own actions, earned it. mom has been saying the long version since at least 1998, by my best estimate. mom never got the credit. nobody at any dictionary will ever update the entry on her recommendation. but the proverb, on the kitchen version, still works in a way the textbook version cannot. that should, in any reasonable accounting, count for something.

i would also like to say, for completeness, that the financial newsletter that uses fool in its name as a deliberate contrarian flag is, in its way, in the same business as mom. it tells subscribers, in a serious tone, that the smart-looking play is usually the trick. it asks subscribers to keep notes. it would, if it knew about her, endorse mom’s version of the proverb without revisions, except possibly to add a footnote about diversification.

i have, somewhere on the internet, watched “parenthood”, the 1989 film, in which several mothers across several generations deliver, between them, approximately fourteen variations on the second-person proverb without ever quite naming it. that film is foolscap-coded. that film is also mom-coded. mom would have liked it. mom would have, at minute forty, said “that’s a different category” at the screen, and the film would have agreed, and i would have been, on my mother’s couch, in 1992, watching her edit a film at the same time the film was running.

i mentioned this to a discussion of what the same financial newsletter charges per year, which is, on monday afternoon, the only other open tab i have for any of this. the discussion concerns whether you should pay to be told what mom would have said for free. the answer depends, broadly, on whether you have a mom. some people don’t. some people have to subscribe. some people have to keep their own receipts.

carla just drifted past the desk, on her way back from the third floor, the training session evidently dismissed twelve minutes early. tab change executed clean. she did not slow down. by tradition that means everything is fine, or about to be the opposite of fine, and i won’t know which until tomorrow.
