The document tells a story about a boy who hammers nails into a fence each time he loses his temper or argues with someone. Over time, with his father's guidance, the boy learns to control himself and removes nails from the fence. His father tells him that while the nails can be removed, the holes they left behind will remain, just as hurtful words can leave wounds that are not easily healed. The rest of the document provides advice and superstitions about friendship, love, and life.
