He even said I was nice, pretty, and cute! He really likes me and I want to look nice if he is going to ask me out!

He's already said you are nice and pretty. Why change your look?

And where do 7th graders go "out" My son is six grade and to impress him, you would be good at Wii or video games to even get his attention.

Well I'm grade 8 and I no what you mean about trying to look good for this guy
But are you going out somewhere? Or just at school? Do you have curly or staight hair?
Sorry can't really help
