No. The girl is still a stranger and it's a totally creepy thing to say to a stranger. And, no surprise, girls think you are gay. Yep, they smile. Yep, they say thanks. To their new gay friend.
Pua is not about picking up girls is about impressing boys. They impressed you. That's their goal. That's how their business model works. Let's have the maths revolve around you instead of them...
How much was the bootcamp? How long ago was it? How many times you got laid since then? How many times you normally get laid in the same amount of time? What's the difference aka your return on investment?
Peace,
