I voted YANBU and here’s why. I was raised by my grandparents because I had an abusive father and my mother had mental health issues and was broken down by his abuse. The physical abuse wasn’t great, but the verbal abuse was absolutely soul-destroying. One of the things he would do is just scream at me, “CHEW MORE QUIETLY,” or his favorite, “DRINK SOMETHING,” as if making just normal chewing sounds was dehydration. The amount of times I should mention I already had excellent table manners and chewed with my mouth closed; I believe he had misophonia because I do too, but when people normally chewing bothers my misophonia, I don’t take it on them because I’m not a fucking arsehole. When my grandparents got elderly, listening to them eat a sandwich was like the noise of being on a building site, but I didn’t say anything because, again, I’m not an abusive prick.
So only you know which of these situations is what happened:
- Your daughter has appalling table manners and was chewing with her mouth open, very loudly, next to your husband, and rightly got a (mild) telling off.
- She was chewing with her mouth closed, displaying fine manners, but chewy candy just happens to make a lot of noise when you eat it.
If it was the first, he should still have said, “Please chew with your mouth closed.” He’s her parent, not her sibling; he’s supposed to teach her, not snipe at her. The problem with what he said is that it neither gives her an opportunity to learn or to do better - wtf is she supposed to do? Just not chew?
If it’s a one-off, we all get snappy sometimes. And think on it no more. But if he makes comments often to the children that are things they can’t fix (stuff like yelling at them for sneezing too loudly), that’s when you have a problem.
(I realize this is heavily affected by my own experiences; I just wanted to provide this alternative point of view).
