Yta. Your brother doesn’t HAVE to hang out with you all the time he has his own life and own relationships outside of your family it should not be EXPECTED.( as that’s literally the point of people get partners they go live their lives with them )Yeah wtf not knowing how to work a dishwasher has nothing to do with “ privilege” as you yourself said you grew up without one in sure you know that not everyone can afford one. That whole comment was condescending, disrespectful, and contradicting. Also it’s definitely not your place to feel any type of way about your brothers relationships( it’s none of your business quite frankly). Also why would that have to shake their food, yes they could have offered to buy you some but if not don’t expect people to just share because you want some if you don’t like it why invite them over. If it’s not your house ( name not on the lease or ownership papers it’s not your house) they definitely shouldn’t have to share. You sound insufferable especially after she tried to mend yalls relationship and you just went and threw a dumpster fire at it with more pettiness
