Chris asked, "But you forgot it?" Dad said, "Yes, I forgot it." Chris asked, "Why did you forget it?" Dad said, "I forgot it because it isn't important." Chris asked, "If it isn't important, why are we learning it?" His dad said that was a good question. He said, "You're learning it because your teacher thinks it's important." Chris asked, "Can't you call my teacher? Can't you tell her that this isn't important?"
