As a child, I did not like to sleep. I woke every morning at 4:00 am (sometimes earlier). My parents made a rule that I was not allowed out of bed until 5:00 am. So every morning, I would lie wide awake, waiting, waiting, waiting. My sister would be sleeping peacefully in the bed next to mine. When at long last 5:00 am arrived, I would creep downstairs soundlessly in the dark and switch on the TV at lowest volume and watch Tom & Jerry. We were not allowed to watch cartoons, but at that hour no one was stopping me.
