Michael invited his mother over for dinner. During the meal, his mother couldn't help noticing how beautiful Michael's roommate was. She had long been suspicious of a relationship between Michael and his roommate and this only made her more curious.
Over the course of the evening, while watching the two interact, she started to wonder if there was more between Michael and the roommate than met the eye. Reading his mom's thoughts, Michael volunteered, "I know what you must be thinking, but I assure you, Joanne and I are just roommates."
About a week later, Joanne came to Michael and said, "Ever since your mother came to dinner, I've been unable to find the beautiful silver gravy ladle. "You don't suppose she took it, do you?" Joanne said, "Well, I doubt it, but I'll write her a letter just to be sure."
So he sat down and wrote: "Dear Mother, I'm not saying you 'did' take a gravy ladle from my house, and I'm not saying you 'did not' take a gravy ladle. But the fact remains that one has been missing ever since you were here for dinner."
Several days later, John received a letter from his mother which read: "Dear Son, I'm not saying that you 'do' sleep with Joanne, and I'm not saying that you 'do not' sleep with Joanne. But the fact remains that if she was sleeping in her own bed, she would have found the gravy ladle by now. Love, Mom"
