Hall of Infinite Doors
It does indeed feel awkward, you are walking to your car, and the kid is following 10 feet back to see what you do next. You loop around a tree that is near you car to add some pizaz to an otherwise boring turn, and then open the car door, and climb inside. The boy follows due to the nature of the game, but he hesitates near your door. You move around a little in you car while he follows and then you get out, close the door and lock it behind you. You have him! Just like Peter Piper and the rats!
