"Marking family and personal occasions in this way has become increasingly important to all of us; these events intersect long, quiet weeks with laughter and company. And here’s the often unacknowledged benefit to keeping watch on a widower: With my grandparents dead and my friends all around my age, he diversifies my social life as much as I do his. He gives me a perspective on the city we live in that my peers simply don’t have. We spend our time together talking about our dissimilar lives and the things that matter to us, reminiscing about his many rich years, and looking up old poems in the vast library that lines the walls of his house. He is my friend and I miss him when I am away. As it turns out, nonagenarians are good company".
