There's this guy in the same program as me, so I often see him between classes/in the common area. He's a couple years older, so we aren't in any classes nor do we have any common friends. I can see an attraction between us. every time we see each other, we can't stop staring at each other, and whenever he comes in the common area when I'm sitting alone reading, he always either stands near me as possible while waiting for his next class, or talks to people sitting by me that he knows (he seems to know everyone he's very popular- a school athlete). From what I've said (I'm not exagerating anything!) does he sound interested? Should I approach him, and if so, what should I do/say?
