Many people said that childhoood the best stage of their life. The child is born in good family, he or she has parents who love and take care of him or her. The child can go to school,they learn new things and write .They play many types of games with friends and schoolmates. The child is not worried about an adult's problems like to have everything ready for work, pay bills, survive till next paycheck etc. Kids don't pay attention to problems like policy, global warming, high criminality or problems of the third world. Then childhood is the happiest time of one's life.But when one grows up all the the enjoyment vanishes.The responsibilities come on them.
But if we see the orther side. A person is born in poor family, can't go to school, can't learn how to read and write, can't experience new things or can't play with other kids. Or a child has parents who abuse him or her. Such childhood is a nightmare of one's life. After some time the person manages to get out from such situation or the situation simply improves. Then the better stage of one's life starts.
In conclusion, childhood is the happiest time of a person's life in most cases. It depends on circumstances and the number of bad childhood is not small either. One can't chose where he or she will be born.
