I'm glad to smell my family and friends. I know the smell of the afternoon in my office, warmed by sun, as well as the smell of the advent of spring. Before opening my eyes on awakening this morning, I could smell that the dogs and cat had joined me in bed, but my husband was up. In the next hour, I smelled mown grass and a waft of cloves in the park; the mustiness of a raincoat taken out of a back closet; when the toast was ready; and the beautiful, straw-like smell of the top of my son's head. I relish it all.
