I'm mostly in a gamer nerd type of group. But I'm also in the "quiet group" (the one that never talks in school) atau "the one that chicks stares at" (either because I'm handsome atau someone to laugh at because of my sexuality =.=...sometimes both)....If those two are considered social groups xD I don't really care for social groups.
We aren't the outcasts because we're all still friends with everyone else. I'm not sure... the thing with our school is that even though we do have "groups", we all still talk to and are sorta friends with each other. I guess we're the diverse group, because we're all of different nationalities: Tanzanian, Zimbabwean, Indian, Persian and Ethiopian :3
When I was at school, I didn't really have a solid group of friends, I just floated around from group to group atau just left school grounds during lunch breaks. So I can't say I've ever felt that feeling of 'belonging' to a group I guess :/
