The irreplaceable void PART 3

Time passes by very quickly, and soon another year has passed. It's winter, and its Christmas time. Everywhere the Christmas spirit is in every passer by.. Christmas carols and frantic shoppers.. but alas, my son got into another trouble. When I was about to knock of from the day's work, the post office called.
