Last night, I dreamed that I was teaching a class of 20 how to break into my house by picking the lock. Then I tried to make my getaway in my car, except my car was a white Apple iCar, and the ignition slot was on the roof of the car, so I had to climb out and insert the key, and I woke up right as I was thinking, “This interface design is horribly inefficient.”
