A man is in bed with his wife when there’s a knock, knock on the door. He rolls over and looks at his clock. It’s half past three in the morning.

I will happily ignore that he thinks, and tries to go back to sleep.

However, a louder knock follows.

“Aren’t you going to answer that?” asks his wife who is also awake now.

Not wanting a row he drags himself out of bed, goes downstairs and opens the door to be greeted by a man standing outside.

“Hey mate,” says the stranger, “can you give me a push please?”

“You’re joking! It’s half past three in the morning. I was in bed fast asleep,” says the man and shuts the door.

He goes back up to bed and tells his wife what happened.

“That’s charming”, she says, “Don’t you remember that night we broke down in the pouring rain on the way home, you had to knock at that house to get help?  What would have happened if they had refused us?”

“OK, OK” he says in resignation, and gets out of bed again, gets dressed, and goes downstairs. He opens the front door but can’t see the stranger anywhere.  So he shouts, “Hello, do you still want a push?”

In the distance a voice cries out, “Yes please.”

Still unable to see the stranger he shouts, “Where are you?”

“Over here, on the swings.”
