This one stopped me cold. Never thought of that before. And he's right. By Miller Williams from "Poetry 180, A Turning Back to Poetry," edited by Billy Collins.
I think the death of domestic animals
marks the sea changes in our lives.
Think how things were, when things were different.
There was an animal then, a dog or a cat,
not the one you have now, another one.
Think when things were different before that.
There was another one then. You had almost forgotten.
