Is OTHER wrong in the post ? POST : i (16M) just turned 16 two days ago and none of my friends said happy birthday, not in school or in person. neither did my parents.

i complained about this to my sister (21F) and she said that i need to fuck off with this petty bullshit and that she has a dissertation to do and that i am an asshole for disturbing her and then my parents agreed i need to not concern her with "petty shit" AITA?
