My wing man and I approached a group of ladies sitting at a table and the approach could have gone better - I said, "You ladies don't look like you're having fun" to which one of them replied, "A piece of information, you never tell a girl she's not having fun". Despite that we started talking and I got my target to dance with me a few times and we were having a good time. A little later into the night I came up to the same girl to ask her to dance (mind you I've been working other sets that night and have been bouncing around playing it off as being social) and she said "No. I'm good" and I said "Ok, you're good" then out of nowhere she reiterated "I said I'm good". I revisited her table where it was just 2 of the 3 girls talking about 30 minutes later and as I approached she didn't even look at me, raised her hand, and said "We're talking" twice like I was some kind of deaf child. She left shortly after that and her friends left maybe 20 minutes after that.

I'm still new to the game and know where I messed up in my approach as it was laid out clear for me by the one chick but I'm still confused as to why and how this girl went from fun to frump in just a short amount of time. My wing man even told me that while I was in the bathroom they said that I was her type (which I don't know exactly what to say but yeah). I'm not being AFC about it, just curious how to handle this situation or if anyone can shed some light on it. These girls supposedly hang around there on the same days me and my friends do. This girl seems like the uptight kind to me.

Don't view every set as a puzzle to be solved, sometimes the solution is to move on. Maybe her dog died that day, or you look exactly like an ex that cheated on her, or maybe she's just a killjoy bitch.

The bottom line is that there are a thousand reasons why someone might not be receptive, and none of them are worth investigating in any particular instance. From what I read in your post, this chick was borderline hostile; in general, just avoid negative people, they fuck with your head space and attitude, and can leave you analyzing what you did (which from what I can tell is honestly attempt to be friendly) and looking for issues with it.

Don't sweat it my man, it's one thing to be able to plow through a bit of a bitch shield with confidence, but it's another to disregard social calibration. There's plenty more chickas that want to chat and dance with a fun guy

Yeah from what my friend told me these girls didn't liked being talked about in the open (when I said "You girls don't seem like to be having fun"). So yeah... I'm heading back out there tonight where there's gonna be some even more targets out and about. Thanks for the rise man, I need to keep my mind clear and my not care attitude
