Why would a guy avoid up close eye contact??

Anonymous
This guy made direct eye contact with me last year for about a minute. his head was turned toward me when he was walking in another direction. he was just staring, no expression nothing. I looked away after a while because I didn't know what to do or think.

He is in one my classes this semester. Has made eye contact with me in the hallways (briefly). He stood next to me once in the hall & I turned to him but then he sort of jumped and was looking at some poster. He was also teasing me during presentations in class (almost poking fun at me about my hair, what I have talked about outside of class-I am sure he has listened in to a few of my conversations and used irrelevent stuff my friend and I have talked about in presentations for class) but he seemed to be making fun of a guy I was sitting with in class-I think the guy picked up on it..

I noticed today when I had to give him something in class he avoided eye contact with me when I went up to him today? he was just looking straight ahead. I thought he may have liked me but not so sure now. What does this avoiding eye contact mean?
