Judy Lerner thinks that perhaps this note, written by her granddaughter Jacklyn when she was 7 years old, may be a child’s version of being boiled in oil. Jacklyn had reached the end of her patience with her little sister and dashed off a warning:
 
’‘Dear Allison, I am sueing you! You are going to be punished in a quart of law. Love, Jacklyn.’‘
