Suddenly I remembered a game Sarah and I had played when we were eight and had competed to see who could stay underwater longer. I thought of how I’d watched her through the aqua pool water, fearing that I would surface before her. Even then I’d wanted so badly to win. Then, after a while, when I wasn’t sure I could hold my breath a second longer, just as I was about to give up and declare her the winner, Sarah would break the surface. I concentrated hard on staying under another two seconds, so I could beat her soundly. Then I broke the surface, and my lungs had filled with fresh, crisp air.
