'potentially' And 'reality"

A man and his wife are awakened at 3 o'clock in the morning by a loud
pounding on the door.

The man gets up and goes to the door where a drunken stranger, standing in
the pouring rain, is asking for a push.

"Not a chance," says the husband, "It is three o'clock in the morning."

He slams the door and returns to bed.

"Who was that?" asked his wife.

"Just some drunk guy asking for a push," he answers.

"Did you help him?" she asks.

"No. I did not.  Its three o'clock in the morning and it is pouring rain
outside!"

His wife said, "Can't you remember about three months ago when our car broke
down and those two guys helped us?  I think you too should lend a helping
hand, and you should be ashamed of yourself!"

The man does as he is told by his wife (of course!), gets dressed and goes
out into the pouring rain.

He calls out into the dark, "Hello! Are you still there?"

"Yes," comes back the answer.

"Do you still need a push?" calls out the husband.

"Yes!  Please!" comes the reply from the darkness.

"Where are you?" asks the husband.

"Over here, in the garden, on the swing!!" replies the drunk.
