I am in college and I've had this guy for a couple of classes last semester. This semester he is in another class with me. I want to talk to him but I don't know what to say. I got intimidated since one of the other girls attempted to talk to him and he pretty much just gave her short curt answers so it kind of deterred me from speaking to him. Should I smile at him or would that be creepy? I don't know...any tips?
