Do I talk to her for a specified amount of time and then ask her out if the conversation flows? Do I just make her laugh by teasing or saying funny shit that I like too and then ask her out? Do I do something of the above but expecting some signals that I am not sure about? Does anything change if the girl is in my social circle? How do I talk to her alone and not only when she is with her friends? How do I establish that connection needed before asking her out?
