About a week later, his roommate came to him saying, “Ever since your mother came to dinner, I’ve been unable to find the silver plate. You don’t suppose she took it, do you?”

He said ,”Well, I doubt it, but I’ll email her, just to be sure.” He sat down and wrote :

Dear Mother: I’m not saying that you ‘did’ take the silver plate from my house, I’m not saying that you ‘did not’ take the silver plate But the fact remains that it has been missing ever since you were here for dinner. Love, your son. Several days later, he received an email from his Mother which read: Dear Son: I’m not saying that you ‘do’ sleep with your roommate, and I’m not saying that you ‘do not’ sleep with her. But the fact remains that if she was sleeping in her OWN bed, she would have found the silver plate by now, under her pillow… Love, Mom.
