A boy was born to a couple after eleven years of marriage. They were a loving couple and the boy was the apple of their eye.

One   36  , when the boy was around two, the husband saw an opened medicine bottle. It was 8:30 am and he was almost   37  for work, so he asked his wife to  38   the lid on the bottle and put it in the cupboard. Busy in the kitchen, the mother  39   forgot the matter. Seeing the bottle, the boy picked it up playfully and  40   the liquid in it. It was a medicine  41   for adults to be taken in small dosages （剂量）. When the boy fell down, the mother hurried him to a(n)  42   where he died. The mother was terrified. How could she  43  her husband?

When the heartbroken father returned and saw the dead son, he  44   his wife and said just four words. What do you think those four words were? The husband just said, “I  45   you, darling.”

The husband’s totally  46   reaction was positive. Their son could never be  47   back to life,so there was no point in finding fault with the mother. Besides, this would not have happened   48  he had taken the time to put the bottle away.

The mother had also lost her only  49  . What she needed at that moment was  50   and sympathy from the husband. That is what he gave her.

Sometimes we spend time asking who is   51  , only to miss the opportunity to enjoy the  52   in human relationships we could receive by giving each other support. Why don’t we  53   someone we love for the “mistake” they didn’t make on purpose?

Treasure what you  54  , let go of all your anger,  55   to forgive, and selfishness and you will find fewer problems in the world.
