"I'm the line leader!"

At daycare, the students take turns being the line leader when the class goes outside to play.  At home, Alice is always the line leader. On the way to the potty, she runs ahead of you shouting, "I'm the line leader!  Don't tinkle on the floor!"  Of course, her parents manipulate this desire to be line leader. Whenever she is dawdling (out the door in the morning, on a walk, going to the car) all you have to do is ask innocently, "Who's the line leader?" and Alice will run ahead yelling, "I'm the line leader!"
