需要推一下吗 Need a push?

A man is in bed asleep with his wife when there is a rat- a-tat-tat on the door.
He rolls over and looks at his clock, and it's half past three in the morning. "I'm not getting out of bed at this time", he thinks, and rolls over.
Then, 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 and there is man standing there. It didn't take the homeowner long to realize the man was drunk.
"Hi there." slurs the stranger, "Can you give me a push??"
"No, get lost(走开!), it's half past three. I was in bed." says the man and slams the door.
He goes back up to bed and tells his wife what happened and she says "Dave, that wasn't very nice of you. Remember
that night we broke down on the pouring rain on the way to pick the kids up from the baby-sitter and you had to knock on that man's 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 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)."
