Many people from other countries think that the happiest time of a person's life is when he or she is an adult. But I think otherwise. I think that the best time of a person's life is when he is a child. Why do I think that? I don't really know. Maybe, because a little child doesn't have any big problems. I'm a teenager. And I must go to school, do my homework and a lot of other boring things. I have little time for myself. So, a child can do almost everything he or she wants. He or she has a lot of free time. And I am jealous of him or her.
