At the tender age of about 10, I got my first lesson on the subject of cleaning up after oneself. We’d gone to visit Gramma and Grampa in Watertown, Mass., a little way out of Boston. I always liked visiting their home, a really old-fashioned place with a parlor – a small room off the living room, home to a couple of rocking chairs no one actually sat in. In fact, the big set of double French doors to the parlor was rarely not closed.
