In the old days I use to go to the Como/Rice massage parlor. One time I went in and the girl who came to the door was my friends ex girlfriend and some one that I always had the hots for. She was totally embarrassed but I said I really wanted to see her. First time with her was one of my best experiences ever. I continued to see her for about 3 yrs until she left the business.

Calling a 10 looks provider up, one time...

who recognized my voice and remembered all sorts of things about me but yet,
me not having a clue who she was even after she told me where we had met multiple

Only until 6 or so hours later, I figured it out!

Yep.  Was out to dinner with my family a couple of months ago and sitting kitty corner from us in my easy viewing were 4 beautiful women having drinks and dinner, two of whom I have had the great pleasure of meeting.  Probably a good thing they were engrossed in their conversation to notice me.  That really might have been awkward.

I was out to dinner with my SO in downtown MPLS, and as we were bundling up to leave, a provider with whom I had a regular relationship was bundling up to leave along with three friends.  We saw each other, but did not react.  The SO and I proceeded up the street to a holiday concert, and, yep, there was the provider and her friends in Orchestra Hall.  

When I next saw the provider, she commented on how uncomfortable the incident made her; even though she had known quite a bit about the SO, seeing her in the flesh made it "real.

once at the MIA

Years ago i spent a little time working in a peepshow. I had a very recognizable customer one morning then later seen him at the art museum where I was taking my little brother to an exhibit. I made my brother kinda dash and hide with me but couldn't tell him why.
