The other day I was visited by a memory from the early days of my marriage, when my wife and I still lived in the old house on the south side of San Antonio. This was when we were both in our early twenties and nearly broke all the time, always on the verge of eviction from the house we rented for $520 a month. Still, we had a lot of friends back then—more friends than we have now—and these friends were always coming over with bottles of wine and half-finished paintings they wanted to show us, poems they wanted to read us, songs they wanted to play for us. There were a lot of parties back then—parties almost every night—and Madeline and I, still in the early years of our marriage, still childless, were somehow always hosting these parties in our house, though I can’t remember ever sending out formal invitations or even ever shopping in advance for them. They were more like spontaneous affairs, and all we really provided, aside from good will, and a kind of open door policy when it came to strangers, was the house itself.
