>>5 lol When I was new in class, all I wanted to stay invisible. I didn't like being popular, but my classmates though the other. So they started talking to me. It was that time when I stopped being shy and I became cheerful and greeting everyone ^^ Now I'm befriending everyone I met. Give it a try.
It might be a happy story for you too.
Or, if you still don't want to talk to them, trust me: one day you'll have. But you can dress all black and pretend to comemorate something. Or someone. Dunno. BUT, it is not going to work if you have school uniform hahaha
So, my advice is to go and talk to them. You'll met good friends and it will be better for you to be a positive-thinking-person.
