“Certainly, words can be as abusive as any blow. . . . When a three-year-old yells, “You’re so stupid! What a dummy!” it doesn’t carry the same weight as when a mother yells those words to a child. . . . Even if you don’t physically abuse young children, you can still drive them nuts with your words.”
