wake-up call

I've always been a late riser, and when we would visit Dallas as kids and teenagers Duncan would get frustrated with me for sleeping in. I remember one morning when I was in a sleeping bag on the floor of Duncan's room. I woke up with a start, sat up and looked around confusedly, saying "What happened?" Duncan, who was sitting up on his bed, said, "What do you mean, 'What happened?'" I said, "I was just lying here and then it felt like someone hit me in the face. What happened?" "Nothing," Duncan said. "You just sat up all of a sudden and said 'What happened?'" Years later, in an effort to clear his conscience, I think, Duncan reminded me of this event and admitted that he'd thrown a tennis ball at my head.
