Have you taken out all the nails?

When I was tidying up my office cubicle, I saw the post-it note on the wall. I decided to re-tell this story I once heard. Sorry that it has to be written in English due to technical difficulty.

A boy loved to throw his tantrums. One day, the father brought him to the garden and said "Every time, when you have thrown your tantrums, nail a nail onto this block of wood and if you did not throw any tantrums for a day, you may remove one nail from this block of wood." The boy did what he was told. Initially, he nailed more than 10 nails onto the wood for many days; but subsequently, the nails are fewer and soon, he began to remove some from the wood. One day, he managed to remove all the nails. He was so happy and brought his father to the garden. "Dad, you see, I have removed all the nails" said the boy happily. The father said, "Son, I am happy for you. You have learnt to control your temper. However, have you seen the holes on the wood? The holes are not removed. Just like when you threw your tantrums, you hurt someone. The tantrum is over but the hurt may be still there. We should not make 'holes' in our relationship for the 'holes' made will take ages to mend. "

Today, I look at the "wood" (a piece of post-it note) on my wall in my office. I only left 1 more "nail" (pins) to remove. But there are a lot of holes made. I hope those who I have hurt before, will forgive me.

May I be able to remove the last pin and stop putting new ones onto the post-it note; May I only plant good seeds in my heart and not overwhelmed by anger; and lastly, may all who read or do not read this, be well and happy and never fall into this trap of anger.
