(i) Old people describe childhood as the best part of life. They remember it fondly, recalling happy days, jolly games, fun at school, jokes with friends, and endless discussions on various topics.
(ii) The father scolded the boy because the boy was crying about having to go back to school after the holidays. The father, reminiscing about his own childhood, expressed a wish to be a boy again and go to school.
(iii) When the father wished to be a boy again, a magical transformation occurred: suddenly, the father became a little boy, and his son became a grown-up man like his father. As the little boy, the father had to go to school again, and he did not enjoy it as much as he thought he would.
(iv) The old people forget to mention or tend to overlook the unpleasant aspects of childhood. While they remember the happy and carefree moments, they may not recall the difficulties and challenges that children face, such as the boy's distress over going back to school after holidays, which seemed trivial to the father but were significant to the boy.
