The Plan.

You wake up and it's August and it's 7 AM, an hour after you went to sleep.
You get up, close all the windows and then turn the air conditioning on, setting it to maximum. You shave and shower. After the shower put your best clothes on: shirt, tie, long trousers, the whole works.
You then go to your room and get back into bed, and sleep until the remaining hours of daylight are over.
