I've never known where to put my body.
I forget to swing my arms when I walk. I forget to put my hands out when I fall. I flap my arms when I'm stressed and jump up and down when I'm excited and I've been bullied so much for all of those things.
I love that ballet tells me exactly what to do. It's so precise and prescriptive. I know where to put my arms. I know how to turn my legs. The transitions are prescribed--it's like my dream.
I've struggled in other styles of dance because it's all "Feel the music! Do what your body wants!" I don't know what my body wants. That got trained out of me when I was in elementary school. But I know I'm doing ballet right. The fact that there's a clearly-defined 'right' is great.
(Caveat: I mean like a healthy ballet class where the focus is on learning. Obviously abusive and body-shaming ballet schools are not safe spaces for anybody)
