In this Second Half, love looks nothing like what I thought it was supposed to look like throughout my First Half. If I thought it should be pink, it has shown up in blues and oranges and sea-greens. If I was certain it was round and smooth, I now know it can be amorphous, linear, with jagged edges or holes. There are no rules, there is no template. But there are two basic kinds of love. A friend recently put it beautifully when describing her own very long-term love relationship: there were never any fireworks, but there were Christmas lights.
