The girls confused on why i have opened them. They smile, are friendly. but there still kinda awkward about me being there talking to them.

Im not just cold approaching here, im socially putting myself out there for everyone to notice, opening sets, being freindly, starting convos with anyone cool i see.

I got IoI's from the set i wanted to approach, and i get this shit?
it feels like a needle shot everytime trying to PU girls, every little small detail, action and movement seems to be written in stone with fucking women lol.

enough rant, anybody please share some advice with me on what to do when this happens? thanks

Sorry, could you be a little clearer with what you want to solve?

If I were to take it at face value, it looks like you're over-analyzing things, not to mention you're paying attention to petty details. If you're having fun in the convo and focusing on the conversation, you shouldn't be getting hung up from these little things.

Don't sweat it. More often than not, it's good to ignore those little things.
