i think the last female friend i had was when i was 14-15.she was pretty much the only female spoke to semi regularly,and she stopped speaking to me when i autistically got nervous and didn't say happy birthday to her right after she told me it was her birthday(my mind froze when she said happy birthday and after 3 seconds i wondered if i should say happy birthday,and then wondered if maybe it was already too late). i remember her all of a sudden jumping to her friends table with a sullen face and whispering. after that we sort of stopped talking to one another.when we saw each other,we would just look awkwardly and then try our best to not talk to one another.
weirdly enough she always treated me incredibly kind,and i still feel sorry for not saying happy birthday to her. the way she acted was unwarranted probably,but like, friends are friends and sometimes you do something without meaning to so yeah.anyway, that was quite some time ago...
