Dancing: Samba

I've always had an intense enjoyment and love for dancing. Mostly just the movement of my body in a rhythm that is mine. Free, flowing, moving and creating heat within. Megan has been kind enough to introduce me to this Samba troupe, which I'm a bit apprehensive about. If I look at my feelings about my experiences from week to week, I see that although I attain that heat and intense enjoyment, there is a time during the practice sessions where I experience anxiety. Samba is not easy. The ladies leading the group are very technical and demanding. I say this because after a session of fun booty-shaking, the leader says, "Ok ladies, I've hand-held you long enough, you need to be stepping it up next practice." And not with a smile or "GOOD JOB" but with a serious tone and nature. And that was it. In thinking about it I realize that perhaps not only was I not going to feel that connectiong to dancing when the expectation is a bit higher for skills that I truly have to accept that I may not have or may not be interested in pursuing to the degree that is needed for the troupe. So I will continue participating until it stops being enjoyable. I assume that I am the one that makes the decision of whether or not something is enjoyable, right? But I must come to the conclusion at some point that perhaps what the troupe needs is not me. ?? I'll try a few more sessions and make an informed decision.
