There is currently a freshman boy (I can tell he's a freshman by the kind of computer he has) sitting about fifteen feet away from me in the library, listening to music on his computer. Without headphones. This means that WE ALL get to listen to his weird moany music.
Earlier, a freshman boy carried on a conversation on his cell phone, and didn't even realize it was not really appropriate until I laughed at him. (I seriously didn't mean to laugh at him. It just kind of. . . came out.)
