This post reminds me of his passage in his book in which some kid pushes his daughter on the playground.

He fantasizes about walking up to the kid and pushing him down lol. But I believe at the end he just grabs his daughter and leaves.

"I remember taking my daughter to the playground once when she was about two. She was playing on the monkey bars, hanging in mid-air. A particularly provocative little monster of about the same age was standing above her on the same bar she was gripping. I watched him move towards her. Our eyes locked. He slowly and deliberately stepped on her hands, with increasing force, over and over, as he stared me down. He knew exactly what he was doing. Up yours, Daddy-O — that was his philosophy. He had already concluded that adults were contemptible, and that he could safely defy them. (Too bad, then, that he was destined to become one.) That was the hopeless future his parents had saddled him with. To his great and salutary shock, I picked him bodily off the playground structure, and threw him thirty feet down the field.

"No, I didn’t. I just took my daughter somewhere else. But it would have been better for him if I had."

Oh, his fantasy was actually worse than what I remembered.
