Update:
Well, this is the type of girl who is constantly approached by other guys - including guys from the dance classes. I saw it with my own eyes.
She is good and she knows it.
I met her again in the dance class. This time I tried to be a bit cold and distant with her, and tried as much as possible to seem like I didn't care. Which is kind of odd, considering that I tried direct game the last time we met . But that was the whole purpose

.
During the classes we swap partners from 5 to 5 minutes.
The two times I got her I could feel that there was some connection. She would make a smile and initiate a bit of a conversation.
The other teacher interrupted us to correct my posture and sayd something like "Don't do it like this, don't be afraid to get close to her, she won't eat you".
When we wen't back to dancing she said something like "Yeah, I was eating you".
What the fuck was that?
Don't really know what she ment, but it got me thinking. Back then I made a poker face and continued dancing of course. Maybe it was a shit test just to see how I reacted.
In the end of the class I didn't say goodbye to her, which may even sound rude.
Well, I prefer the framing of a proud motherfucker than that of an AFC.
I think there is still a chance on having something.
I mean, it appears to me that she shows some signs of interests but maybe it could be just wishfull thinking. Any input would be appreciated.
