This day hasn't begun well. I overslept and didn't close the blinds at the east side early enough. Now the flat is an oven. Brunch almost burned because my parents called by phone right then. And as soon as I sat down to eat a friend called and asked if I could give him a ride home. Which I did. Came home drenched in sweat (the air-conditioning in the car isn't up to the task if the car heated up in the sun) and thirsty. Went under the shower as the first thing.
It can only get better from here. I hope.
