There is, of course, a lesson in it regardless.
Once there was a girl whose father was angry at her mother, so he went away for a time. During that time, the girl was sent to live with an evil grandmother, who beat her and called her many bad things, and burned her hands. When the father returned, the girl had resolved always to be a good girl in the future so that such things would not occur, and never to anger him again.
I should have listened better to this story before having children with such.
