I deserve a bloody medal, crawling into work on just two hours' sleep. I got in at 6:45 this morning, and set my clock for the very latest time that I could get up and still make it to work: 8:45. I have that hollow, somehow grey feeling that only comes with sleep-deprivation. Am I hungry? Am I tired? I don't know. But I do know I'm very, very irritable. So don't mess with me today, sunshine.
