During my childhood days, I had some friends while I was in the primary school. However, today, I do not know the whereabouts of most of them. I know it is so with you also. Truly, 20 children don't play together for 20 years! Granted, their whereabouts are unknown to me today; but certainly none of them is at the same spot I left them. Some have distinguished themselves in their various fields, making outstanding contributions to humanity.
