What do say/do when a girl says "yes"?

[jjmcray]

Ok so there's this girl that I really like. We know each other really well, and I think she likes me too. I plan to ask her to go out with me, but I don't know what to say or do if she says "yes." I imagine it would be weird if I just said "Thanks!" or "Great!" or "Really?"... So, what should I say/do?

You show some enthuasiasm "Great!", '"Cool!". Then you make a plan to get together, something like "Are you free_______?"

Actually that's not weird at all, but "Really?" would make you sound shy and unconfident of yourself.

Smile. Don't go crazy trying to look happy, but if you're happy she said "yes", let it show. Something like "great!" or "cool!" or "awesome!" would be fine. Then, you need to set up a date. If you just ask her out then walk away, she's going to be confused, so you need to affirm the fact that you do want to go on a date with her. Movies are ok, but if you do that be sure to go out for food before or after the film. Otherwise, you just sit there in the dark and don't get to know each other at all--it can be very impersonal for a first date. Just make sure that whatever you do, you have some time to talk to each other (but there should still be an activity, maybe bowling or mini golf, to help eliminate awkward lulls in conversation). You don't have to plan every detail right then, but you should make sure to get her phone number (and give her yours!), and an idea of when she'll be free, so that you can talk soon and figure something out.

Also, if you're not right about to head off in seperate directions, offering her your hand is a good move. Don't grab her hand, just hold yours out towards her and let her choose whether she wants to take it or not.

Well, I already know her pretty well and she knows me pretty well, we know each other's phone numbers, talk on the phone a few hours every night, so I don't really have to worry about "getting to know her," I guess.

Thank you for your help so far.

Umm...the first thing I think of is...
"Great! Well I will see you then! Bye!" Then walk away!
It just should be a one liner and then get out. There is no need for anymore conversation.
Or you could do the:
"Well I will pick you up at ___ and I will talk to you later! Bye!"
It's a toss up but it should be short and sweet!

You could always just say something like, "Awesome, so you wanna go to ______ on _____" or you could even offer to take her somewhere then and there [depending on when you ask her out. If she says yes, don't act surprised, but act how you really feel, which is presumably happy. As others have said, just smile, say something like "Cool" or "Great" or even "Wow" and then follow it up with a comment. I don't know if this works on all girls, but you could always say something to flatter her, like that you never thought a girl like her would say yes to a guy like you, but because you already know each other pretty well, you might not want to do that.

Underground_Network said a really good thing to say to her, I've never asked a girl cause I'm like a loner at school... But I do like a girl.

Update:
I told her I liked her today and she likes me too. :)
Just waiting for the right moment to ask her out...
