DON'T ask her right away

DONT ask right away! if u do u would really regret it! Know more about this person before asking them out. Make sure this person is your type. if He or she isnt your whole life will be a disaster! when the time comes All u do is go up talk to her for a couple minutes(dont Wait to long!)and then say"well (person's name) i was wondering if u wanted to go out with me?"There u go!
Good luck!
