oh dude. Keep going. This thread is really interesting and builds up a lot of conversations. I learned a lot of things in this thread like the "who are you" opener, the response and funny traitment of "will u take us photo" question and the danger of saying for payment.
I WILL DO THE SAME WITH YOU SOMETIME.

Do not practice only on the opener skills. If i was you i will push the things with the girls/targets until the fclose or making them gf/ltr.
"Salut" guy is right. You should improve a lot of skills when you make an aproach, not just one. With every succesful approach practice on creating attraction, impression, comfort etc push the things until the end. Do not let your target so easy so you want to go to next. Insist on the flirt. Once on the beach i saw 2 girls and my friend asked me for approaching them. I walked face to face to them and i said "hi" looking at one of them. They completely ignore me. (if u were me u would quit it and go to the next). I make another 3 approaches to the same girl. One apr. was when they playing voleyball. I join. She get bored and left me. I approach her again walking on the beach. We talked in front of so many peoples and she showed a lot of lols, it was extremely obvious. I recognized that all eyes was on us ^^ and i left. I let her make approach now. Talk, have fun, go out and we meet together but i fucked things/attraction because of too much real storytelling of me being a good guy and i wasnt interested to her. I just accomplish my goal -> she is interesting on me. I should learn more different skills and not quit it in this phase of female-to-male-attraction.
keep going and push the things until the end.
