Ok, so there's this girl i thought that liked me because she always looked at me when i wasn't looking, would turn away when i would look at her, was very nice to me, and smiled when talking to me. I send her a friend request on facebook and 2 messages, one saying hi another if she could confirm my friend request so i can be verified that i go to a school (i changed schools and wanted to join my new school network). When i come back in like 2 hours, i have the option to invite her to friends again, which means she ignored my previous offer, and obviously logged on and also ignored my messages sent(cause she didn't reply or resend friend request if she accidentaly ignored it). Any idea why she would do this?

Ah yes, i did talk to her once before in the 3 weeks i've known her when i was helping her with school work =D
