I’ve been hobbling around on one foot for a week and thinking a lot about gratitude. It all began last Sunday, after a first date with someone I met online. He took the train from Manhattan to meet me at a lovely restaurant near me. We sat for about two hours, dining al fresco on a gorgeous Summer afternoon. As I began walking towards my car, my left foot cramped up. I thought it was a fleeting thing and would work itself out by the time I got home. So, I made plans to take a walk with a friend, but my foot just kept getting worse. Our walk lasted about 10 minutes, as I limped around the block and collapsed on my coach. “What’s going on with my foot?” I thought. This is weird. I thought I’d sleep on it and all would be good in the morning.
