Dear Sir，
    I think it is important for children learn how to do chores and help they parents with housework.It is not enough to just get good grades at school.Children these days depend on their parents too many.They are always asking， "Could you get this for me？" or "Could you help me with that？" Doing chores help to develop children's independence and teaches them what to look after themselves.It also helps them to understand an idea of fairness.Since they live in one house with their parents，they should know that everyone should do their part in keeping it clean and tidy.Our neighbors' son got into a good college and during his first year，he had no idea how to take careful of himself.As a result，he often fell ill and her grades dropped.The earlier kids learn to be independent，the more better it is for their future.
Mr.Smith
