Reflecting on last night, there was one girl who I didn't think I had a chance with (Not that she was out of my league per se, just that she was 5'11 (her words) and I'm 5'9 so didn't think it was there at the time).

Basically I would put my arm around her waist and move her around, say if she was drifting out of the circle we were dancing with I would pull her back in and she was fully receptive to it, zero resistance to me holding around her waist or whatever.

Looking back I'm pretty sure this was a really strong IOI, but what do ya'll think? I'm quite new to the scene
