Mom visits son for dinner

A mom visits her son for dinner who lives
with a girl as a roommate.

During his meal,
his mother couldn't help but notice how
pretty his roommate was. She had long
been suspicious of a relationship between
the two and this had only made her more curious.

Over the course of the evening
... while watching the two interact, she
started to wonder if there's more between
him and his roommate. Reading his mom's thought, his son
volunteered,

"I know what you must be
thinking, but I assure you, we are just
roommates."

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 your mother
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 mom, After your visit me, the silver plate has
been missing. I'm not saying that you did take the silver
plate from my house, and I'm not saying
that you don't take it, 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
don't 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
