Over the course of the evening, while watching the two men interact,
she started to wonder if there was more between John and the roommate
than met the eye.

Reading his  mom's thoughts, John volunteered,  "I know what you must
be thinking, but I assure you,  Mike and I are just roommates."

About a week later, Mike came to John 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?"  John 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 Mike, and I'm not
saying that you 'don't' sleep with Mike.  But the fact remains that if
he was sleeping in his own bed, he would have found the gravy ladle by
now.

Love, Mom"
