Having hard times concentrating

Seriously I am having trouble concentrating in class. I was actually "fishing" in Maths Class. The only matters that keep me awake are my friends' chatter and the girls passing by the classroom. *Haha* Really hate myself for that. I cant believe I was actually checking the girls out. But the girls nowadays are really tall, not to mention they are attractive as well. *Hehe* Recently, I found out that I was not that tall after all. Reason? Simple. There are girls who are actually taller than me. Frankly speaking, I was totally stunned when the girl passed by me that day. I was wondering if only she could "donate" some of her "height" to those shorter girls.X) Anyway, I really hope I will be able to concentrate better in the future.
