       A man and a woman had a son eleven years after they married. They had a happy family and the boy was the apple of their eyes. When the boy was four years old, an accident happened. One night the father was very tired after work,so he asked his wife to meet their son and take him home. The mother was very busy in the kitchen,and she forgot about it.

       Later the boy lost his way in the street. When the mother found this, she went to look for him, but she couldn't find him. Then she went to the police station to ask for help. She was very sad and didn't know

how to face her husband. After hearing the bad news,the father humed to the police station. When he saw his wife,he didn't blame her. Instead he said,"l love you,darling ! "

       "If I had picked him up or found this earlier,this would not have happened," the father thought. He

thought there was no point in blaming anyone. His wife also lost her only child. What he could give her

was just consolation and understanding. Several weeks later,with the help of the police,they finally found

their lost son. From then on,they became closer than before. When something bad happens,people always spend lots' of time  blaming others instead of giving others support. Try to learn to forgive,and then you

will find the world is much more wonderful.
