It is funny how the occasion imperceptibly changes, like the light, at an inconstant rate. At any given glance you may see that the dog has rolled over in his sleep, or the trees have lost their leaves. Morning drains inexpressibly into lunchtime, or Christmastime. Overhead the geese are migrating, just as they were the last time you looked. You wash the dishes, turn around, and it is summer again, or some other time, or time to go.
Teaching a Stone to Talk, Annie Dillard
