Summarize: How often one hears children wishing they were grown up, and older people wishing they were young again. Each age has its own pleasures and pains, and happiest person is the one who enjoys what age gives him without wasting his time in useless regrets. Childhood is a time when there are few responsibilities to make life difficult. A child is fed and looked after by his parents. It is impossible that he will be ever again so much without having to do anything in return. In addition, life is always representing new things to the child-things that have lost their interest for older people because they are too familiar. A child finds pleasure in playing in the rain or in the snow. His first visit to the sea side is a marvelous adventure. But a child has his pains, he is not as free as he wishes to be and as he thinks older people are. He is continuously being told not to do things, or being punished for what he has done wrong. His life, therefore, is not completely happy.
