Here's Luck by Lennie Lower

Stanley has made a complete mess of things. Better that I had reared a guinea pig. I knew he was like that. I knew it right from the first. When I first saw him, bald, florid and toothless in his nurse's arms and heard them mouthing that vile, age-old slander, "Isn't he like his father?" I shuddered. When he was crawling about the floor and I was falling over him in all directions, I said, "That child is a menace."

Later, when he came home from school and said the teacher caned him because he deserved it, I remarked to his mother, "There's something wrong with that boy. He's unnatural."
