A boy was born to a couple after eleven years of marriage. They were a loving couple and loved the boy
very much. When the boy was around two years old, one morning the husband saw a medicine bottle open.
He was late for office so he asked his wife to cap the bottle and put it back into the cupboard in the bathroom.
However, his wife, busy in the kitchen, totally forgot the matter.
The boy saw the bottle and playfully went to the bottle fascinated by its color and drank it all. It happened
to contain a kind of medicine for adults with poisonous and side effects. When the child broke down, the
mother hurried him to the hospital. But he finally died. The mother was shocked. She was terrified how she
was going to face her husband.
When the desperate father came to the hospital and saw the dead child, he looked at his wife and voiced
just five words. The husband just said "I am with you, Darling". The husband's totally unexpected reaction is
a positive behavior. The child is dead. He can never be brought back to life. There is no point in finding fault
with the mother. Besides, if only he had taken time to keep the bottle away, this would not have happened.
No one is to be blamed. she had also lost her only child. What she needed at that moment was comfort and
sympathy from the husband. That is what he gave her.
If evervone can look at life with this kind of viewpoint, there would be much fewer problems in the world.
Take off all your envies, jealousies, unforgiveness, selfishness, and fears and you will find things are actually
not as difficult as you think. Sometimes we spend time asking who is responsible or whom to blame, whether
in a relationshlp, in a job or with the people we know. By this way we miss out some warmth in human
relationship.
