Why do guys stare, but don't look away?

This guy in class stares at me but doesn't look away when I catch him. And when he isn't staring at me, his head is just resting on his hands and his eyes look 'open'. More than usual at least. What does this mean?

Well, when I do catch him looking, he doesn't smile or anything. He just stares straight into my eyes. He doesn't even look away.
