I and a dog

I and a dog

A dog and I are standing.
I didn’t take a step.
He didn't take a step.
I wonder
Where did this dog come from?
He wonders.
Where do I come from? I'm afraid.
He is afraid.
And how do I know that he is a good dog?
And how does he know that I am a good man?
Strange dog, I thought.
Strange man, he thought and left.
