If you want to know if you should ask her out, The answer is YES! Just be calm, cool and collected about it, and do not put allot of pressure on her (this comes from personal experience it is not fun when the guy does that, you are a guy, right? Not being funny, just want to make sure this is going the right way). Just nicely say something like hey,are you free tomorrow night? Wanna go to a movie, dinner, coffee, whatever you fill in the blank. If you make her laugh allot, I bet she says yes.
