So, there's a cute guy in my freshman class. He seems to be very popular. He's never alone. And I see him flirt with girls. He sat on a girl's lap one time. I don't know if that was his girlfriend or if he was trying to be a pain. But I've also seen him do one of those tricks like tapping someone on one shoulder and be on the other side. I've seen him do that to a girl before

He's very cute, I can't stop sneaking glances at him. But I don't want him to think I'm a stalker either. He's seen me look at him before. I'm really shy and I just can't gather up the courage to talk to him. What should I do to be attractive to him and get his attention?
