Read it through once

He called himself "Satan," and he spoke with an air of infinite melancholy and yet with perfect courtesy. At first we took delight in the oddity of the name and in the gravity of his manners; afterwards we learned to love the beautiful gentleness of his ways. He was kind to children, and he had a way of talking to them as if they were grown persons; he never scolded or punished, but sometimes he refrained from answering, and that was as instructive as a lecture.
