[Pete]

I really like this girl that i am really crazy about, she is on my mind 24/7 but i am so shy and get really nervous when i walk near or past her because i really wanna ask her out but i just get so shy and just cant.. she also told me last night that she wants a boyfriend and i told her that she will get one because she is cute and gorgeous and all that but i don't think she gets the hint i like her We're not really good friends like i can talk to her on facebook no problem, but when it comes to talking to her in real life i get so nervous and everyday i dont talk to her when i get home i just feel so sad I can't even say hi, let alone actually ask her out
