Mum comes to visit her son for 3 days in London where he is studying. She finds out that her son lives with Vicki, a young female roommate. Mum couldn't help but notice how pretty her son's roommate was. She suspects a relationship between the two, and this had only made her more curious. Reading his mum's thoughts, the son volunteered... "Mum, I know what you must be thinking, but I assure you, Vicki and I are just roommates."
About a week later, Vicki came to the son saying... "Ever since your mother left, I've been unable to find the silver sugar bowl. You don't suppose she took it do you?"
"Well, I doubt it, but I'll email her, just to be sure." So he sat down and
wrote: "Dear Mother, I'm not saying that you "did" take the sugar bowl from my house, I'm not saying that you "did not" take it. But the fact remains that it has been missing ever since you left and went back home. Your loving Son."
Several days later, he received an email from his Mother which read:
"Dear Son, I'm not saying that you 'do' sleep with Vicki, 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 sugar bowl by now. Gotcha!".
