Ok, my internet game isn't up to par with my real life game but that's not why I am here. I had a one night stand with a girl. I didn't really game her to begin with. I was social proofed and convenient, it more just happened. In the morning she hugged me goodbye and thanked me for a fun night. She's quite petite so I picked her right up and squeezed her. She seemed receptive but no plans to communicate or meet in the future where discussed.

I know she has a bf who may read her fb messages or be hanging over her shoulder. I would like to send her a message that conveys certain things.

1. Non neediness obviously.
2. That I am discreet.
3. Witty or any other dhv.

The problem is I need to do it in a way that if her bf read it, he won't suspect anything has happened in the past. It must seem random. I was going to say something along the lines of...

"Hey, I know you don't know me but I've seen you around town. You seem chill so I figured I would say hi."

For one that sounds AFC to me. Second, she may think that I actually don't recognize her and that I think she is someone else. That may help or it may not. If anything I want her to be able to read it right in front of anyone, yet only her and I know the true meaning. I barely know this girl. The point of the "I know you don't know me" serves two purposes.
1. It's a joke because while we were in bed naked I introduced myself to her as though we had just met and shook her hand. Broke the ice a bit with a joke since I didn't know her all that well.
2. If her bf reads the message he will assume I never met her before and am just yet another orbiter.

What ever I do she must get the impression that I am slick and discrete.

and no I usually don't go for girls with bf's.
