From time to time I have to go out by myself as I don't always have a wing with me.
Now when I found out about pining I first went out on my one's and chatted to some random cool looking guys but I would leave and approach women chat for a bit then go back to chat to them, now after a couple of times of them seeing me do this THEY started doing it and they even started winging me.
I assume there thought process went something like this "wow this guys talking to random chicks and getting a good response, the chicks in this bar must be very friendly so I guess its OK to talk to girls in here."
I thought I would test it in different circumstances to see how far I could take it
