Fiancee's Mother

Dear friend Abby:

I have been engaged for almost a year. I am to be married next month.
My fiancée’s mother is not only very attractive [read Hot!] but really great and
understanding. She is putting the entire wedding together and invited
me to her place to go over the invitation list because it had grown a
bit beyond what we had expected it to be. When I got to her place, we
reviewed the list and trimmed it down to just under a hundred... then
she floored me. She said that in a month I would be a married man and
that before that happened, she wanted to have sex with me.

Then she just stood up and walked to her bedroom and on her way said
that I knew where the front door was if I wanted to leave. I stood
there for about five minutes and finally decided that I knew exactly
how to deal with this situation.

I headed straight out the front door...............
There, leaning against my car, was her husband, my father-in-law to be.
He was smiling. He explained that they just wanted to be sure I was a
good kid and would be true to their little girl. I shook his hand and
he congratulated me on passing their little test. Abby, should I tell
my fiancee what her parents did, and that I thought their "little test"
was asinine and insulting to my character?

Or should I keep the whole thing to myself, including the fact that the
reason I was walking out to my car was to get a condom?
