Step-by-step explanation:
The question refers to the character Bud from the novel Bud, Not Buddy by Christopher Paul Curtis. Bud broke rule number sixty-three, which suggested that he should never lie because he was in a situation where he believed that telling the truth wouldn't work out well for him.
