I had just opened a group of 3 girls standing at the bar at a party and I was talking to the girl in front of me, a HB7. Having only just arrived, I still had my backpack on me with an umbrella sticking out on the left side, where my target was standing.

Once in a while I leaned in, effectively moving the handle of my umbrella in and out of her way and she started touching it. I then threw in an exaggerated and slightly neurotic "D-d-d-d-don't touch that. It's MY umbrella!" and eventually I gave it to her if she promised to give it back later. It's important to immediatly shift your attention back to the girl you were talking too before. I used some patterns, isolated her and kissclosed in the rain.

I hope this helps someone.
