By the way I wouldn't recommend Sasha's opener; "don't panic I am not a robber, I just want to say you look amazing" as it just gets things off to a bad start. I read on another pua forum someone had a bad reaction with this line. Instead I would keep it more lighthearted. Avoid negative terms like "don't panic" and "robber" and say something like: "Hello, excuse me, I'm not going to try to sell you something I just wanted to say you look amazing". If you understand psychology you will know that when you mention negative things people will always feel more negative than if you hadn't mentioned them.
