There is nothing funny about child abuse, so I hesitate to tell this story. But there is a point to it, so please bear with me.
Back in the day when parents did not see anything wrong with occasionally giving their kids a smack, there was a very young boy who believed that if he shut his eyes tightly, no one could see him. When his father was angry, the boy would close his eyes and feel safe. When he got hit anyway, he was initially shocked. But eventually he learned that hiding did not make him safe.
