And the time sundials tellMay be minutes and hours. But it may just as wellBe seconds and sparkles, or seasons and flowers.No, I don't think of time as just minutes and hours.Time can be heartbeats, or bird songs, or miles,Or waves on a beach, or ants in their files(They do move like seconds—just watch their feet go:Tick-tick-tick, like a clock). You'll learn as you growThat whatever there is in a garden, the sunCounts up on its dial. By the time it is doneOur sundial—or someone's— will certainly addAll the good things there are. Yes, and all of the bad.And if anyone's here for the finish, the sunWill have told him—by sundial—how well we have done.How well we have done, or how badly. Alas,That is a long thought. Let me hope we all pass.
