OPEN GUYS!!!! need to know what these signals mean.?

okay so im in high school.I like this really cute guy and he is always staring at me.I always smile back but i get so shy.And whenever im with my friends he will kinda act weird like...not a jerk but diffrent but he always is smiling at me when im around him.Plus whenever he gets up he goes to sharpen his pencil BUT IT IS ALREADY SHARPENED and then he just stares at me when he sharpens it.Also he heard that my celeb crush is Ryan Sheckler and now im starting to notice he is dressing like him not too.Whats all this mean...does he like me?
