People were baffled that anyone would be so "embarrassed" or uncomfortable about having a lovely, caring wife. With some of the highest rated replies being:
"You're embarrassed by your wife giving out cookies as a thank you? That's a weird thing to get embarrassed about, having a thoughtful, considerate, kind wife. [You're the asshole]."
"YTA. Even if I wouldn't eat a bag a cookies from a stranger (I would btw, I just know some people wouldn't) I would appreciate the gesture and realize they had gone out of their way to make me feel good. You're shaming your wife for having found a way to express herself despite her shyness. You're embarrassed by someone showing kindness. Wow."
And one person even went so far as to paraphrase a beloved childhood character who would probably have some strong thoughts on the matter, writing:
"Y is for YTA, that's good enough for me! Y is for YTA, that's good enough for me! Y is for YTA, that's good enough for me! COOKIE COOKIE COOKIE COOKIE COOKIE!"
