His son follows his dad's advice. Everytime he gets furious, he hit a nail on the wooden wall. Eventually, he realized that he is able to control his temper as he able to release all this frustration by hitting the nail, really hard, on the wall.
As days go by, the wooden wall is covered by hundreds of nails, indicating how often his son get mad, even on small and minor matters. His son is ashamed and begs his dad to enlighten him on how he can control his temper.
His dad is glad with his son's confession and asks him to remove a nail everytime he is able to suppress his anger. He follows. As days go by and the all of the nails are removed from the wooden wall, he runs toward his dad, expressing his 'achievement' and 'victory' over his bad temper.
'Go and take a look of the wooden wall'. The son realized that there are many holes on the wall. 'You may have removed all the nails that were on the wall, but as the repercussion, these leave the "innocent" wall nothing but holes. Like your words, you may express all these harsh and hurtful words to make yourself feel better but for the listeners, it pierced a hole in their heart. It is pointless to say sorry after committing such damage to your beloved one'
Just for your own sake and pleasure, you end up hurting someone. This action is equally to abusing your loved one physically to make you feel better. Once the hole is there, it is a tough job to fix it. There are many ways to express what you dislike, but hurting them verbally will only make it worse ;p
' You shouldn't commit what you dislike to others. Others will commit what they dislike to you, in return; Unless you like what they don't like, otherwise this war never ends'
