Chris 's uncle used to play doowop tunes and gargle SweetTarts in his driver seat. Chris thought the car smelled hot, but couldn’t explain what that smelled like. It must have been the velvet seat coverings. When the tires hits the curb, Chris knew to start pretending sleep. They would be home in four big turns. But when, after a grocery-stock boy sort of pestering from the uncle, Chris opened his eyes, he saw not the wood-pecker knocker of homes glowing door, but the crimson letters of Kravis Family Dental Office. Uncle said it was time for his vaccinations. Chris knew two things, and they were making his grin ring in his big understandings. The two things he knew were these: dentists don 't do vaccinations; Kravis Family Dental Office shares a parking lot with the Chuck E. Cheese.
