Young guy.

So there is this guy I have been scoping out for the past few weeks. He works at my company..I know..another coworker...but they are the best to fool around with. Anyway he is on the young side..maybe 21..and cute but not in what I would normally be into. Kind of skinny..but great eyes. I'm not sure what is attracting me to him. He has this sorta lost puppy look to him most of the time and I just want to understand him. He mostly does him own thing and keeps to himself. I think I will start some interactions between us and see what kind of vibe I get.
