Since a few weeks I stepped my game up through practicing game. Last week I was abroad in Germany for a study trip where we collaborated with German students. Besides working on the project we also partied.

There was this German girl who gave mixed signals to me. She took every opportunity to touch me, initiated dancing with me, holding my hand many times but sometimes she acted a little cold. My friends al expected me to close her, I tried it by subtley leaning in, with no succes.

Maybe I was way too subtle with the closing and should have acted more direct so I knew where I stood. In case she wasn't interested, why do girls sometimes spent 2 hours dancing with a guy when she doesn't want to get closed?

Bonus question: what causes LMR?
