Phil, very good point made there, they could possibly be texting their BFs. That idea didnt pass my mind, but I won't use it as an excuse not to approach. I'll open a nearby set in close proximity first and see what happens.

I've tried something similar before where I saw a bunch of girls all on there mobiles and opened with something like:

"Guys, whats going on here, what are you doing all on your mobile phones" (with a smiley face) and got a friendly response.

Last nights scenario however, neither of them were on their phones.

I've also tried busting girls bulls for being low energy like:

"guys, why aren't you on the dance floor, come on get up" (which never seems to work).

I'm starting to have the new mindset that if I see a set which looks awkward to open due to certain situations then they would have been hit on less times than other girls giving me an edge if I do open.

Anymore Ideas, please let me know.
