when ever u see a guy u like take a quick look at him out of the corner of ur eye. do this for a couple of days and even as little as 4 of 10...he likes u. If u like him just ask him out! most guys r way too shy to ask u out and if they're looking at u as i just said they like u and if u just ask him out you've done yourself a favor. Remember even the tufest guys can be shy when around a girl they really like!

P.S. im a guy and this used to (and sometimes still is for a girl i REALLY like) happen to me
