Old people say that childhood is the best part of life. They look back at their childhood and remember all its happy days, the jolly games, the fun they had at school, the sweets and cakes they used to eat, jokes they used to play and endless discussions they had among friends about almost every topic. Perhaps, these old folks are right. And all in a moment, the father was a little boy and his son was a grown-up man like his father. And the father, in the shape of a little boy, had to go to school, and I can tell you he did not like it at all. A child's troubles may seem small to grown-ups but they are very big to him.
