A guy was invited to an old friends' home for dinner.
His buddy preceded every request to his wife by endearing terms, calling her Honey, My Love, Darling, Sweetheart, Pumpkin, etc.
The guy was impressed since he knew the couple had been married almost 70 years, and while the wife was off in the kitchen he said to his buddy, "I think it's wonderful that after all the years you've been married, you still call your wife those pet names."
His buddy hung his head. "To tell you the truth, I forgot her name about ten years ago."
