Good: a new girl saying "You're a very good leader, I don't feel like I'm on my second lesson."
Bad: that doesn't happen all the time.
Mixed: doing lindy fairly well with an experienced girl, who manages to act very very distant. Makes me wonder about that body odor article.
What's really bad is when a dance with an experienced girl just falls apart, but that didn't happen tonight. Actually catching the rhythm in the music is still the riskiest part for me.
