In a new community, you may suddenly have no social group. If you get involved in your new community, you will begin to feel at home there. You will have to create opportunities to meet people and make friends. Sit next to a different person every day in class. Begin conversations with people you do not know.
People naturally like to talk about themselves and receive compliments.
If someone eats alone in the cafeteria every day, join him or her. If someone looks lost, offer to help him or her find the way. If someone gets a new bicycle, ask him or her about it. Being friendly can help you develop lasting friendships. But remember, it can take a long time.
