so i was  sitting in class and there's this dude who sits next to me who's always trying to chat. we were talking about work and stuff and i told him that i work part time (about 15 hours a week) and he was like "oh okay cool". then about 20 minutes later, he asked what my expenses are (like car, phone, etc) and i just said "that's kinda none of your business" and continued working. he then got kinda flustered and seemed upset, and was saying things like "oh i just wanted to know because you don't work very many hours". i'm kinda an idiot when it comes to social interaction sometimes, and i was already feeling kinda shitty, so i don't know if i was being a dick or not.
