well...i can kinda relate to what your saying because at uni, no one knew i was into fish and for the first year, i was the most popular girl in my class, always going out, clubbing, doing everything and anything with all the people in my year. then once i invited all my friends round to my house and they saw my tanks, and they seemed to think it was cool but i was kinda crazy! now when i start to talk about my fish, the girls are like "what the hell...what are you talking about?!!!" and the guys are like "and there she goes again...always going on about the fish...why don't you just fry them all and have an easy life?!!" but i don't care and i just go on about my fish anyway even if no one's listening and now when i come into class and sit down, people actually ask me if my fish are ok!!! so i kind of forced all the people in my class to get used to me loving my fish, because i won't hide myself or stop a hobby because of anyone, and i mean anyone. so if your friends get bored when you talk about your fish then they aren't real friends! personally i don't care whether the people in my class talk to me or not, and i don't make efforts to talk to anyone, but people always come up to talk to me, so that's how i differentiate between people who accept me for who i am and people who don't!
