Here you will find the Poem Knock On The Door of poet Conrad Potter Aiken
Knock on the door, and you shall have an answer! Open the heavy walls to set me free, And blow a horn to call me into the sunlight, And startled then what a strange thing you shall see! Nuns, murderers, and drunkards, saints and sinners, Lover and dancing girl and sage and clown Will laugh upon you, and you will find me nowhere? I am a room, a house, a street, a town.
