Hey mmrizmy - when I started out in pickup, my biggest problem was going indirect and not showing my interest. So I decided to change my game, I decided to go direct - every set I have opened hooks a million times more easily and every set I have gone direct on, I have closed!
So, my adivce to you is something along the lines of:
YOU: Where does this bus stop go to?
HB: It goes to XXX
YOU: XXX? I thought it went to YYY?
HB: No, definately XXX haha
YOU: Oh thats alright, because I only came over here to flirt with you.
HB: blushing and smiling
Then go from there..
If you need any advice or tips, PM me.
