The girl who is incomparably more attractive to everyone else in the library. And who you spend 9 hours everyday sitting in each others line of sight and you try admire but its pretty damn hard to over 9 hours without seeming creepy. Then you do half as much work as you should do because you're daydreaming over whether she has a boyfriend and crucially whether she looks at you in the same way. But, well, it's all over by friday. Makes the hours in the library a bit more exciting.
