I Fail at Life.

I'm at the library waiting for a book on course reserve that I need to finish a study guide for my nutrition final tomorrow. I got here 20 minutes after someone checked the book out. It has a two hour circulation time. I still have 40 minutes before it's due. How does this always happen to me? This is the 3rd or 4th time this semester that someone has checked it out 10-20 minutes before I try to. Argh.
