The young wife was in tears when she opened the door for her husband. “I’ve been insulted,” she sobbed. “Your mother insulted me.”
“My mother!” he exclaimed. “But she is a hundred miles away.”
“I know, but a letter came for you this morning and I opened it.” 
– He looked stern, “I see, but where does the insult come in?”
“In the postscript,” she answered. “It said: ‘Dear Alice, don’t forget to give this letter to George.'”
