I have to tell you the truth

An elderly gent was invited to an old friend's home for dinner one evening. He was impressed by the way his buddy preceded every request to his wife with endearing terms such as: Honey, My Love, Darling, Sweetheart, Pumpkin, etc.

The couple had been married almost 70 years and clearly, they were still very much in love. While the wife was in the kitchen, the man leaned over and said to his host, 'I think it's wonderful that, after all these years, you still call your wife those loving pet names.
The old man hung his head. 'I have to tell you the truth,' he said, 'Her name slipped my mind about 10 years ago and I'm scared to death to ask her what it is!' :-)
