Tired

These few days I kept feeling tired although I really didn't do much in the day. I think it must be due to all the late nights. Sometimes, I amaze myself by managing not to fall asleep even when I am already super tired. But now, I really just want to close my eyes. I can't remember much of the geog stuff I have studied today. :( My memory is FAILING me, which is a sign of 'maturity'. *Er hems* Where is my memory power when I need it? Come to think of it, there are too many nitty gritty things to remember though. Actually, the stuffs are quite interesting. It's just that somehow, I find it different, or should I say, more difficult to recall anything when I am reading something for exams as opposed to reading just for leisure. This is so weird.
