I really like a girl and I want to ask for her number. I only see her in one class at school.
Most Helpful Girl
Many many options here let me give you a few:
The cocky guy: hey I just met you and this is crazy, but here's my number so text me maybe?
Sorry had to put it out there on a more serious note.
Just ask her, say hey can I have your phone number?
If your not that confident make an excuse-
For your class lie and say you don't really understand the homework assigned and if you could have her phone number so that you can text her with questions.
This can go both ways if she doesn't understand then give her your number so she can text you will questions.
Write it in a year book, at the end of the year just put your number in her year book she'll be flattered
You could even ask your friends if they have her phone number and be sneaky and text her that way1
