Once upon a time there was a boy who fond of reading. However, he was very poor to buy any books. That was the reason that he had to borrow books from a rich man who had a lot of books. The

boy knew clearly that he has to finish reading the books he had borrowed and return it to the owner as

soon as possible. A rich man, who was ready to lend any of his book to the boy, read few of his own

books. With time going on, the boy read a lot but finally became a famous writer in his time. Though

the rich man had such many books, he remained a man with little knowledge because of he seldom

read his books.
