Java Monster!

I tried this energy drink today called Java Monster "Loca Moca". Pretty good, but now I'm bouncing off the walls! I gotta do something, go somewhere.

OK, question. There is this guy at work. He is handsome, sweet and successful. He is not married, but I think he has a girlfriend. He works in a different building than me, but I'm always running into him. Several times now at company meetings and functions, I catch him staring at me, then when I catch his gaze, he very quickly turns his head away very deliberately, very noticeable. In fact, if it wasn't so dramatic, I would think nothing of it, but it keeps happening. He also seems nervous around me. Does this mean anything? I have no clue, but it seems odd.
