A man and his wife are awakened at 3:30 a.m. by a knock on the door. "I'm not getting out of bed at this hour," he thinks and rolls back over.
A louder knock follows. "Aren't you going to answer that?" says his wife. So he drags himself out of bed, and goes downstairs.
He opens the door to find a man standing there, obviously drunk. "Hi there," slurs the stranger, "Can you give me a push?"
"No, get lost! It's 3:30 and I was in bed." says the man and slams the door.
When he goes back upstairs his wife says "Dave, that wasn't very nice of you. Remember that night we broke down in the pouring rain on the way to pick the kids up from the baby-sitter? You had to knock at the door of that house to get us started again. What would have happened if he'd told us to get lost?"
"But the guy was drunk," says the husband.
"It doesn't matter," says his wife. "He needs our help, and it would be the Christian thing to do."
So Dave gets up. puts on some clothes and goes downstairs. He opens the door, but doesn't see the stranger. He calls out, "Hey, do you still want a push?"
He hears a voice cry out, "Yeah please."
But he is still unable to locate the stranger. He shouts: "Where are you?"
And the stranger replies: "I'm over here, on your swing.".
