So, I have absolutely no problem with approaching girls and striking up a conversation about any random topic. I'm generally a pretty gregarious and outgoing guy. But recently I've been noticing that a lot of my conversations with girls that I'm interested in at bars and clubs seem to fizzle out after a few minutes. I'm guessing it's because I'm not making my interest in her known enough, and that prevents me from flirting rather than just chatting? Because I know my conversational style tends to be "off the top of my head" rather than "trying to flirt." I'm not entirely sure though, because part of me feels like talking to a girl "just off the top of your head" with high energy and good vibes is the best way for you two to get to know each other?
