Since you said please.. Are you guys even friends? Like, have you even seen each other out of school? If not, it'll probably be a little awkward. Just go for it anyway. The worst she can do is say no(she could say HELL NAW, YOU ARE UGLY and make you feel real bad but...) and make you feel sad for a few days. You would get over it eventually. Just keep in mind that you should do it before it's too late.

I agree. Just go 4 it

live a life without regret bro, alway's weigh out what you can gain vs loose. she rejects you, you loose nothing. she accepts, you could gain everything. live by this saying and you'll never look back going "I should have done that but now its to late"
