One of the strangest phenomena at OU is the way that people sleep in the library. Now, the idea of people falling asleep hunched over a book is pretty normal to me - been there, done that. It's a little bit weird to see, but part of student life. But what's really odd is the way people do it here - the lie down on the couches, put a jacket or something over them, and sleep with the abandon of people at home in their beds.
It takes a great deal of trust for total strangers - after all, when you are that deeply asleep, you're pretty much helpless. I just can't imagine doing such a thing, and even after all this time, it has never ceased to be very strange.
