Muted jazz music bleeds from the walls of the dance studio. My sister and I stand outside and watch, through the glass windows, the varying figures of the dancing pairs: men of assorted heights in jeans and colored button-downs, women in heels and dresses and skirts of subtle hues of green and blue and black. Some of the couples, the more experienced ones, move like waves on a breezy spring day, undulating as a unit across the wooden floor. Other couples sputter like the animatronic creatures at Chuck E. Cheese. In the whole room, there is only one moving mouth. It belongs to a woman who appears to be the instructor, standing to the side, watching the dancers and counting the beats of the music for them.
