Sorry for noob question, is there any solid faq that I can point to , I can read it. I am. I am reading this forum and filtering/bookmarking solid inputs that I see myself applying.

Consider this Scenario : I am doing solo approaches at a mall/Grocery store.

I start with "Hey, this is super random but I just wanted to say I like your hair/shoes/tattoos/top". Assume she says thank you and/ smiles. and consider this happening for 3/10 approaches

How do I structure the conversation after she says thank you?
