I have been sleeping all the time. In school mostly and i hate it. I don;t know why, i think that i sleep well in dorm, but still i can easily fall asleep. It will happen more often if the lesson is boring. If the teacher can not give the students any good explanation, they (not only me) will fall asleep quickly.
I never feel this thing before. I always wake up in my junior high school. I never sleepy and never sleep on the class. Is it one of the habbits that developed by many teenagers? Is it related to the adolescence? I don't know why (again, i always say "i don't know". Maybe i'll search it later.
