Little Johnny was receiving a severe scolding from his mother for fighting with his best friend.
"Johnny, I'm ashamed of you," his mother said. "Fighting with your best friend is a terrible thing to do!"
"But, Mom," Little Johnny argued, "he threw a rock at me, so I threw one at him."
"When he threw a rock at you, you should have come to me," his mother scolded.
"What good would that have done?" Little Johnny grumbled. "My aim's better than yours!"
