This is my first time writing one of these but this has bothering me and I need to know im not crazy. Yesterday I went to brunch with my aunt, cousins, and younger sister following a sleepover at their house. My mom and siblings have this thing that if someone else is paying or offering you should heavily decline or just get the smallest thing possible, or if theres two of us like in this situation, we share something. I understand that when someone else is paying you don’t go and order the most expensive things off the menu, but I didn’t feel like sharing. My sister wanted pancakes and I wanted an omelette, so I just ordered my own plate instead of sharing with her. We go home and she tells my mom I did this and my mom calls me rude and that I don’t have manners saying my aunt now probably thinks I was taking advantage of her kindness… But i dont think what i did was that egregious?? Does anyone else’s family have this rule because mine always has and it has never sat right with me because my parents wouldn’t think this of their nieces and nephew, why would my aunt think this of me? To me it feels like my mom projects her negative thinking onto other people, she always thinks that other people are thinking the worst, and when I tell her you don’t know for sure she calls me naïve. I know this is not a big deal but it still caused an argument and left a bad taste in my mouth and now im overthinking. So AITAH or is this a normal thing to do??
