The youngster was prone to anger, and his angry words and actions troubled both his parents and those close to him. In an effort to help him manage his anger, his father gave him a bag full of nails and instructed him to drive the nails into the wooden fence in the backyard every time he felt angry.

The boy followed his father's advice and quickly used up all the nails. At this point, his father provided him with another bag of nails. The boy continued to drive nails into the wooden fence, and over time, he noticed a decrease in his anger and an improvement in his ability to control his emotions. He shared his progress with his father, who then suggested that he remove the nails from the wooden fence.

The boy followed his father's guidance and found that he no longer experienced anger while removing the nails. Witnessing this positive change in his son's behavior, the father spoke to him, saying, "You have gained control over your anger. Did you also notice the damage you caused to the wooden fence when you drove the nails into it? Those holes marred the beauty of the wooden fence. In a similar way, the angry words, like the nails, inflict harm on others, even though you have learned to control your anger. The emotional distress caused by those angry words is akin to the damage from the holes left by the nails on the wooden fence, and these wounds can fester in others. You should never exhibit this behavior again in your life."

In summary:

1.    Anger is comparable to a knife.

2.    Just as a person carries scars from a knife wound for life, angry words can leave lasting scars in the mind.

3.    Similarly, the impact of angry words can be enduring.
