It's hard enough to focus on studying as it is. Come on people.
post script - 6:44 pm: It still smells, and I noticed the guy next to me has bare feet! The culprit. He's also the same one that's been playing computer games and watching movies online since I sat down next to him around 4 pm. I think it's time for him to leave (my nares) in peace and do something more productive. Like, possibly, wash his feet and throw out those sandals.
