My 4-year-old son now enjoys posting letters. He has formed the   36   of drawing pictures, writing his name on them, and then    37   the artwork in an envelope. He then insists on   38   his handwork to the neighbors, and a mail box he   39   belongs to the elderly couple who live next door. To be   40   , I didn’t think much of it, but I had   41   to warn my neighbors of the drawings   42   appearing in their letterboxes—I just didn’t have the   43   to do so, because I was a little busy recently.

  On Tuesday of last week, I was walking down to school to collect my son when I   44   Mary, my elderly neighbor,   45   at her mail box. She said, “Jodie, is it your little son that has been posting items in my letterbox to me?” I was at once   46  , “Oh yes, Mary, it is. I’m sorry. I meant to tell you…” She cut me off, “Jodie, I just love his mail. I’ve   47   every item he has sent. You don’t know how much   48   the letters has made my day. I just love them.” While I was walking down to school after our   49  , many thoughts came to me. Mary doesn’t have a lot to fill her days,   50   she was a mother to a number of children herself who receives fairly regular visitors. The small   51   of getting some mail—pictures drawn by the hand of a young child—has brought   52   to her days, just as my visit to my grandparents does.

  I have decided that my son should   53   this practice. He should also start sending some items to his grandparents in Perth as well. It will most   54   make their day.

  It’s doing the little, simple things that can often make a big   55   in someone’s life.
