The document tells a story about a boy who is given a bag of nails by his father. Every time the boy loses his patience or argues with someone, he must hammer one nail into the fence. Over time, as the boy learns to control his temper, he hammers fewer nails each day. Eventually, he is able to go a full day without hammering any nails. His father then has him remove nails for each day he remains patient. Though all the nails are removed, the fence is still left with holes, just as hurtful words leave wounds even if apologies are given. The document continues with additional proverbs and advice.
