Getting used to the failings of old age is hard. But there are certain compensations, such as the loyalty of a lifelong partner. When she decides you haven’t been eating enough eggs and makes you an omelet for lunch, that’s a peak for the day. And then there are friends, in who’s day you are a light. They brighten things too.
This mutual dependence willed by the Creator (why, for instance, this aptitude for conversation, for mutual joys, for an appreciated joke, for happiness in a familiar face?) is a sign that we’ve got what none of the other animals have to this degree. I say, enjoy it.
