a story of a mother and her son

one day, a little girl fell down onto the ground, the boy went over and wanted to help her up.but his mother stopped him and said: " don't do that, otherwise, others will think it was you who knocked her down." another day, the mother was surprised to see that her son just let the fallen older all be.and the son said to his mother:"if i had the strip brought up, you will find that i did."i disagreed with mother's picture.i think the parents should let the children know it is a pleasure to help others who are in trouble.we are living in the society which is the big family for all of us.we should care for each other and help each other.
