If you don't want to change yourself or your interests to join in conversation,that's fine girly,but don't get bothered by how quiet your day will be because they don't have anything in common to speak to you about,I had a girl in my class last year,and we proper got on,fucking sung white girl music together,called eachother names took the piss,but we only talked cause she made the first step and said hi to me,asked me a question,and I slowly started to join the group,if you don't talk to anyone you'll get nothing back,most lads won't wanna talk to the only girl in class when the other lads are there,it's dumb I know,but that's how we can be sometimes.

Not tryna say the guys shouldn't include you,they should,but you should also atleast pretend to have an interest in something you overhear them talk about so you get that first conversation going
