Well guys I know many of you will say this is a noob question or make fun of it but answering it would be really helpful. This girl in my class i have spoken to we're kewl and everything and she smiles at me etc.. irrelevant. Yesterday i was gona ask for her number when we finished class and while we were talking she said she needed to use the restroom. The question is what should my move be. I could do 3 things here.

1) Not give a fuck if people think it's weird or not and wait for her.

2)Don't appear weird and retain my value and leave. Not to appear desperate.

3) Ask her if I should wait for her.

Guys please give your best answers. Appreciate it!

1) nobody else is gonna notice or care, but if she comes out and is surprised to find you still waiting you'll look like an idiot.

2) leaving might make you look like a dick if she was expecting you to wait around.

A decent response when she says shes gotta use the restroom is, "Ok, well I gotta get goin..." to which she either says, "wait hold up ill just be a min" or "ok see ya later" either way makes it obvious what you should do. Other option is to say
"Ok, well I gotta get goin..."but lemme get your number and Ill give you a call later k?" which will probably get her number right there.

Seems like a good answer. Anyone else have something to say?
