I called this 17 years old girl who is in my college yesterday afternoon but she was busy so I told her I call her again at 8 P.M but unfortunately I was in a noisy place that time at 8 p.m so I didn't call but she called me instead and I didn't answer the phone she kept calling me for 3 more times and I didn't answer again and once I got out of the noisy place I called her, her phone was off and today I called again. . .she didn't answer

Next Monday I'll see her in the college. . what should I do and say when I see her? I want to tell her something in a funny way which might make her forget that and get her back to me. So please give me something like this to tell her

I did a BIG MISTAKE here with this girl and that's acting needy [I called her almost 5 times yesterday and today but she didn't answer] she's not someone that I just met I know her for 3 weeks and talked to her about 8 times but I've never been on a date with her.

I usually greet girls I know with something like "Hey rebel" or "hey dork =]" to neg them a bit, sometimes they dont laugh at the dork one, but the rebel one usually makes them giggle a bit and ask me whats up.
