You turn over to your left side, trying to find a comfortable position on this ratty couch. The metal bars are digging painfully into your side.

A few feet from you, you hear the powerful, endless whirring of a half-dozen computer fans. You'd hoped your brain would eventually tune out the noise and you'd fall asleep.

Police sirens zip by every few minutes with distressing regularity. There's no way you'll be able to sleep like this.

Might as well open your eyes.
