What's the difference between a diplomat and a lady?

     If a diplomat says, "Yes," he means "Maybe."
     If a diplomat says, "Maybe," he means "No."
     If a diplomat says, "No," he's no diplomat.

But on the other hand...

     If a lady says, "No," she means "Maybe."
     If a lady says, "Maybe," she means "Yes."
     If a lady says, "Yes," she's no lady.
