So this just happened a few minutes ago. I saw this girl chilling by herself in the main lobby texting away. Me still being a huge newbie in the game wanted to get over my aa. So I chose a seat somewhat close to her and acted like I was doing school work. Finally I worked up enough courage and went with an indirect opener of "you look like you are having such a fun time over there." She smiled and said something like I am waiting for someone. We talked for a little bit then I left because I wasn't feeling the vibe with her. I know for a fact that I was coming off as such a total AFC because when the conversation would die out, she would go back to playing on her phone, and I would keep trying to talk to her. Felt like my approach was completely off from the start and it just went downhill when the conversation stalled out. It was a one sided conversation as well.
Bottom line: I think I know what I did wrong. Went into rapport without building any attraction (minimum flirting), probably should have went with direct approach, didn't maintain conversation well enough, body language and frame was off by waiting too long to open.
Thanks for reading and any feedback would be much appreciated.
