Re: Ploughing and Flakes
Have you heard of Sasha Daygame on YouTube? I think you would find his style appropriate for your question. He stops girls on the way to work, school, etc.
In my experience/observation women who are rushing places are more likely to be cold towards an approach so if I decide to approach someone rushing I go direct as to save their and my own time.
I say take a crack at the hurried girls approach. Pick up is a numbers game so take the shots.
As for your flake I would say you should have turned your text into a statement but whose to say that would have made her more receptive.
Keep at it playboy.
