It was recital day, and all of my students were lined up backstage; these girls formed a perfectly straight line, no taller than my knee. I had been teaching dance since I was an adolescent so I knew what I was doing. My ballet teacher — whom I so badly wanted to impress, even though no matter how hard I tried, she would never compliment me — smiled at the sight. She loved lines, especially straight lines. She examined the girls as she approached me, and she invited me to admire how small all the girls were while they adjusted their frilly lavender tutus.
