Let me in

I will do you no harm. I will be gentle with your things. I will listen respectfully, even tenderly. I will make you laugh. Let me in.

I have almost no science, and my art is a given quantity. My secrets and my mysteries are commonplace. Let me in.

At the end of a stone wall is a man who places his hand on the wall to steady himself. I cannot tell whether this is his property, or whether he is exploring. I have to go. I have an appointment I should not miss.
