I worked as a technician for a company that sold computers. One time a woman was having trouble turning on her computer. I stopped by her house and quickly discovered the problem. She had gotten into the habit of turning the computer on by first pressing the power switch on the computer, then the power switch on the monitor. But somehow, they had gotten out of sync, so when the computer was on, the monitor was off, or vice versa. So no matter how many times she flipped both switches, the computer just wouldn’t seem to work.
