if showing affection, Mary, my new GF.

then start laughing hysterically.

Oh, well, it would be a Kodak moment anyways.

I suppose the best you can do is to just introduce her as a friend, and say that you are in a hurry to get to the theater, then dash off.

I would do my darnedest to run her down with my monster truck.  LOL!

... I don't know hardly anyone here in STL, but for the minuscule chance that I'd run into someone I know from "real life", that would work for me.

Delayed flights are such a pain, and airports and planes are such potentially social places

Just kidding : ).

Call a friend or associate relative to your (or her if she has one) business.

As long as her name isn't "Tanya Tits" or "Bang bang Betty" you can just introduce her.

"Provider Name, this is X, an old business associate. X, this is Provider Name, a friend of mine. She's assisting my explorations into differentiating turtle species by chemical analysis of their shells. Fascinating!

Did you realize that even sans DNA analysis the accretions making up the shell are unique not just to the species, but to the sex? Absolutely! And Provider Name here has some unique insight into the organic content through use of mass spectrometry and gas chromatography ... blah blah blah."

Problem solved. Whoever just approached you is saying "Get me the hell outa here. " LOL

Re: Fuck "em...Let "em wonder...

especially if it's an ex.

and like Hungry said, "especially if it's an ex" lmao

Guys will understand if you want to be left alone with a hottie, ex's won't understand, but who gives a fuck what an ex wants? Female friends, well they are a different story, just letting them wonder will pay dividends in the amount of civvie sex you will get later, especially if the provider is hot. lol
