I don't have any friends?

Sometimes it's better we're by ourselves. Try always being confident in yourself, and friendly. I would start by just saying hi to everyone. Maybe talk about the cl or clwork at first. Ask them if their ready for the test, if there is one. You can ask if they finished, or understood the ignment, only if the ignment was difficult. Just all kinds of things about the cl and things that are related to it. If you talk about the cl and classwork enough, it's usually enough to break the ice and get a feel for the kind of person they are. Then you can start talking about other things. Sometimes people are so busy with everyday life, their not interested in making friends, but I'm sure you'll find plenty of people to be friends with. You seem like a terrific guy. You'll be fine. Just start little by little and you'll have plenty of friends. Good luck.
