Taking solitude in stride was a sign of strength and of a willingness to take care of myself. This meant – among other things – working productively, remembering to leave the house, and eating well. I thought about food all the time. I had a subscription to Gourmet and Food & Wine. Cooking for others had often been my way of offering care. So why, when I was alone, did I find myself trying to subsist on cereal and water? I’d need to learn to cook for one.
