Remember to try and talk about her. My take on the conversation

Me: "Excuse me, I just saw you from over there and I thought you looked really nice, and I just had to come and say hello..."
Her: "Awwww Thanks. (big smile!)"
Me (you never struggle if you're being in the moment): "Yeah it was just the way you were standing there / walking / (what ever caught your eye!). You were in your own little bubble smiling. Maybe its because you love shopping / the sun / etc."
Her: "Yeah i was just shopping for blah / I was on my way to work / Blah..."

After that talk about things that you want in a women... make sure you know what that is... if she speaks shit according your standards... make excuses and leave... if she matches what you're looking for then the rest will come easy.

Fuck girls. They're shit.
