A wife, arriving home from a shopping trip, was horrified to find her
husband in bed with a lovely young woman. Just as the wife was about
to storm out of the house, her husband stopped her with these words:

Before you leave, I want you to hear how this all came about.

Driving along the highway, I saw this young woman looking tired and
bedraggled, so I brought her home and made her a meal from the roast
beef you had forgotten in refrigerator. She had only some worn sandals
on her feet, so I gave her a pair of good shoes you had discarded
because they had gone out of style. She was cold so I gave her a
sweater I bought you for your birthday that you never wore because the
color did not suit you. Her pants were worn out so I gave her a pair
of yours that were perfectly good but too small for you now. Then when
she was about to leave the house she paused and asked, "Is there
anything else your wife doesn't use any more?"
