After my last class I was standing outside with my friend, One of the only people that know I like this guy. Lets call him bob. Well I was standing about 4 feet ahead of bob and my friend was next to me. My back was facing bob and my friend wanted to turn around and look at him.

So after the bell rang my friend came up to me telling me that bob was looking at me. Like he was looking at my whole body and stuff. And she said every time I turned around he would look away and then look back.
I had no idea. =/
so what do you think?

Bob is obliviously checking you out. He definitely attracted to you and he keeps turning around when you look because he is shy.

Talk to him, ask him for his telephone number and if you can give him a call sometime and that way you can speak in private.
