Bored in Science and love problems

Sitting in Science right now. Bored out of my mind. I hate how every school computer is a mac, personally, i'm a PC.

Ok, So there's this girl I like. She's cute, smart, funny, the whole deal. She's a year older than me. I have no classes with her so I only see her during lunch and stuff. What should I do? I really want to be with her but...
1. She's a year older than me
2. She thinks of me as a little brother
3. Her mom is a teacher on campus
Life sucks. Why is life like this? Any advice? Would be much enjoyed :D
