Why would a guy ask me to take of my gles?

Well, I was in an acting cl today and this guy was just staring at me from the time he walked in. He walked all the way aroind from where he was and say across from me. It was weird because he normally does not sit close to me he sits with this girl named Kim. When i looked at him he offered me some skittles, I took it then when the teacher came in the room and told what our ignment was i made a stank face thinking that no one saw me. But he did and he pointed at me and started to laugh. He is a junior and I am a freshmen in college. Then we were paired together and he just kept on smiling the whole time. We had to do what the other person asked us to do and he wanted me to take off my gles.
