Sense of Direction

A little boy, waiting for his mother to come out of a store, is approached by a man asking directions: "Son, can you tell me where the post office is?"
"Sure," says the kid, "just go straight down the street a couple of blocks and turn right."
The man thanks the boy kindly and adds, "I am the new preacher in town, and if you come to the church on Sunday, I will show you how to get to heaven."
The boy grins, in that way kids have a way of grinning when they know something you don't: "Aw, c'mon, you don't even know the way to the post office!"
