A wife arrived home after a shopping trip and sees her husband in bed with a woman.
"Before you leave, I want you to hear how this all came about. Driving home, I saw this young girl, looking poor and tired, I offered her a ride. She was hungry, so I brought her home and fed her. Her shoes were worn-out so I gave her a pair of your shoes that you didn't wear. She was cold, so I gave her that new birthday sweater you never wear because the colour didn't suit you.
Then as she was about to leave, she paused and asked: "Is there anything else that your wife doesn't use anymore?"
"So, here we are!"
