Before this happened, approached a few people just to warm up.
A girl smiled at me at socio, so I approached, held her hand and chatted.

I said few minutes in "can I kiss you" and she said "no"__

I'm hopeful, I will improve the more I kino and go for the kiss, I may have problems with calibration, but should make sense to me with more practice.
