Dozing off

It seems like most of my friends are tired today and they include oppa too. He was like sleeping all the way through the first lecture. He woke up in the gap between the first and second lecture. Then, he slept again during the second lecture. It was funny when he laughed at me when he woke up as he thought that I was sleeping too at that time but in fact, I was just looking at the dirt on my shoes and of course, not concentrating on the lecture. Anyway, poor oppa, his roommate locked him outside his room and he could only go to his bed at 3am which was insane. I slept at 11pm something although I did not read much the night. I am a bit guilty now as I wasn't performing well during the tutorial class today. *sigh. University students should really get enough sleep so that they can pay more attention during lessons. But university students should also make sure that they revise what they learned in lecture, which I am a little slow at.
