She's in my first period class, and I sit across from her at our lunch table. We're not really friends I'd say, but we mess around with each other at lunch and at the end of class. She says that I am "mean" to her, but I tell her that she's mean to me jokingly. I don't have her number or anything, so would it be a good idea to ask for it and/or her myspace when we come back from Christmas Break? And I'm going to try to be less "mean" to her.
