Do you remember the times you used to rush from school, sit behind your parent's desk and put pen to paper (back in those days this was a valid expression) and feel so utterly liberated by the act of writing a letter to someone from another town or country whom you got to know only through the nice smell of paper and ink? And then there was the pleasant wait, for the post person to ring the bell and give you that special letter you've waited for weeks, sometimes even for months. Do you remember?
