SORRY

Its painful not to be understood. Its more painful to know you were at fault. But once time passes,there's little you can do but wish that things were different. Sometimes you loose the most loved person, your sweetest friend, a thing very close to your heart because you were careless for a moment or not sensitive enough t understand! Here's a story where you wish you could reverse time.........

There was once a couple, happily married and in peace, blessed with every worldly pleasure and riches that one would wish. This couple was childless. Ten years after their marriage a baby boy was concieved. This baby was pampered and loved. Years passed and the baby grew. The couple was extermely careful about the safety and upbringing of the boy and adored the him. He started going to school and entertained the family with his baby talks, games and pranks. He became their life.
Once the mother of the boy forgot to close the lid of a tonic and kept it on the floor and forgot about it. The boy drank the tonic when no one was looking and went and slept on the bed. The mother tried to wake the child after two hours and noticed the tonic bottle and went numb. She thought of her son and her husband. When the husband came home in the evening and saw the dead son and the empty tonic bottle beside him, he walked to his wife and said......

I LOVE YOU

The wife started crying in his arms.

After a month the wife asked her husband, why din't he hate her for killing her son..

Can you tell me why?
