Halfway down an unfamiliar block as I’m headed home to dinner, I come upon a small dogwood in full flower. I stop and take in the sight: a profusion of soft blossoms like sweet friends happy to be together, not needing anything more. And here I am, beat from a day that went all wrong, standing on a broken sidewalk, in a city of hard edges, with a chemical bite to the evening air, and even though this is a dogwood tree and I’m a dog person, it makes me feel like purring.
