I banged up my thumb while playing basketball yesterday. It was months since I last played and within the first minute, the ball ricocheted sharply off the rim and jammed my right thumb. The thumb's all swollen now. With it disabled, I have a hard time doing simple things like buttoning up my jeans. Levi 501s have buttons instead of zippers. I wore one yesterday but not today. Normally I'd squeeze the shampoo bottle with my right hand and lather up with my left. Today, I had to reverse things because my righty can't squeeze. Running through my hair felt alien, as if I had never done it before. My hands have separate memories.
