AITA for putting onions and garlic in the food I fed my family after my sister in law said onions were "too spicy"?
So, im a young female and I live with my family still. I contribute my fair share in cooking, cleaning, and I go to school (im currently trying to get a job) anyway recently my brother and his wife, my sister in law has moved right next to us so theyre over all the time for dinner. And maybe three months ago my sister in law saw me cutting up onions and putting them into a pan for dinner and she threw a fit saying onions were too spicy for me to cook and she wasnt gonna eat any if I made whatever it was that I was making with onions, so I had to throw away everything and restart because if I didnt then I would get yelled at, and that's the worst thing so id rather just throw it away. Well the same dinner I made without onions and garlic she said had no flavor. And even though that happened for maybe a week i didnt add onions and garlic and every time i didnt she would complain saying it had no flavor. So since then ive decided to prepare dinner maybe an hour before they come over so they dont see me cutting onions and garlic, ive also made sure to do it when none of my siblings are around so they dont see and in turn tell my sister in law. Well, last night my other brother saw me cutting onions and he didnt care too much he just walked away, but when it was dinner time and we were all eating we got onto a topic of everything's "too spicy" for my sister in law and how she doesnt like ketchup or onions, and that she cant even have takis or whatever, and my brother thinking that it was so funny was saying "oh you cant have onions like theyre too sweet?" And she agreed then was telling him its just how she grew up, she hates them and blah blah blah and so he went "well you dont have a problem eating this dinner" and she was like "what are you talking about? This has no onions in it. She was told not to do that anymore because it makes me sick" and my brother went "but you had no problem with the dinner BEFORE I said anything. So are they too spicy?" And when he said that she started acting like "oh I need some water, oh this food is too spicy, someone get me milk" and I got yelled at. I was told I was the asshole and I shouldn't have done it. But was i the asshole?
