I head over to the streets at evenings/nights (because I'm working all day), and when I approach girls with the who lies more opener they seem to respond well (even if they're in mixed sets). They start instantly giggling and stuff, not sure if that's an IOI.

After I open the sets, I just blank out. I say bye and come back. The only exception was when I asked a girl if it's okay to be friends with our exes. She actually spoke more than I did. But again I chickened out after speaking for three minutes and just walked away. How do I escalate the conversation? Do I ask another opinion or something? I'm like 2 weeks into this PUA thing.

P.S: I'm not hitting clubs in the city since there aren't many to begin with in my town and I'm still 18. So all I do is day game and approach walking sets or stationary sets (sets which are by themselves). Any advice here would be gold.
