It depends on the guy. I don't know why everyone's always so shy all the time. If you think this guy likes you, or if you like him, just go ask him if he likes you, or tell you you like him. What's the worst that could possibly happen? Let's say he doesn't like you, well big deal, then you just let him get to know you, and maybe he'll warm up to you. Maybe he still doesn't like you, then you just move on, so what, it wasn't meant to be.
