Exactly as the title says. My family and I (23f) recently caught up and went to the beach together. It was a lot of fun, despite the blistering heat, and the surf was large, our favourite. Things were going great and my sister (21f) and I made our way into the surge when i said "hey, you’ve got a wedgie" because, well, she did. Badly. I’d noticed it earlier and she hadn’t made a move to fix it. In response she glared at me and swam off, ignoring me for the next hour or so.
Later on shore, the topic came up, and she called me an asshole for "commenting on her body", very audibly and visibly pissed off. I told her I only told her, because its the same as telling someone they have food on my face or in my teeth, you’d want someone to tell you. She yelled at me that her bathers don’t fit anymore and that I’m a mega asshole, and stormed off.
She was cold towards me for the rest of the trip, hasn’t spoken to me days later, and my brother (17m) who still lives with her and my mum told me she spent the entire afternoon pissed off and ranting about me telling her she had a wedgie.
Now, usually I’d ignore this, especially since my sister has always been like this (eg. calling me a cunt because I told her not to sit on the dinner table), but I called my mum today like normal, and she told me I had to apologise to her, and I was in the wrong, and "you didnt need to tell her, she would have felt it". Apparently my sister has put on weight this year and is very insecure about it. Something I barely noticed because I haven’t lived at home in years, and honestly, she doesn’t look it, she’s just grown up and filled out more, in my opinion but I digress.
So AMTA, this whole thing feels like I’m back in high school. My mum treats my sister with baby gloves, despite her being a (in the eyes of the law) adult, so I cant even trust her opinion on if this is apology worthy. How do you even apologise for that? "Sorry you felt like I called you fat?" "I’m sorry you’re upset?" Honestly apologising like that makes me feel like I become the asshole, like I’m saying "im sorry you overacted" instead of saying nothing, and letting her cool off.
