The Negotiation Limerick File

I hate it when my brain wakes me up at 5 in the morning, and I can't convince it to let me go back to sleep, so I get out of bed and by the time I need to be up and about (for, say, a hair cut) then I feel exhausted and ready for sleep. Is it a nap if you go back to bed at 9 AM? No matter, I can't do it anyway.
