This thread reminded me of the times where a girl would go in for a handshake and I flipped it into a game of Thumb-War.
Win or lose... you get to start kino... not just with the hand-game, but after...
I let her beat me, then used C+F and would get playful kino in return. Or, if the girl seemed a bit self-overvalued, I would beat her, and C+F her from that point, and then playfully kino her.
Wow...
totally forgot about that. Time to play that game again. Win or lose... at least you won't be doing a business formal handshake, that conveys... nothing!
If you do find yourself in a situation where a "business formal handshake" is the only appropriate course to take... ALWAYS LOOK DIRECTLY INTO HER EYES when you take her hand, HOLD THAT GAZE, and then... HOLD ONTO HER HAND FOR THREE SECONDS LONGER THAN NEEDED
Never lose eye contact! Muy importante!
