"It doesn't matter." says the wife. "He needs our help, the right thing to do would be to help him."
So the husband out of bed again, gets dressed, and goes downstairs. He opens the door, and not being able to see the stranger anywhere he shouts: "Hey, do you still want a push??" and he hears a voice cry out "Yeah please."
So, still being unable to see the stranger he shouts: "Where are you?"
And the stranger replies: "I'm over here, on your swing(秋千)."
