I found myself very suddenly wide awake long before the dawn of Christmas Day. I left opening my stocking until my great-uncle and aunt would have woken, and I could open it on their bed, the quilt wrapped about my shoulders, while they received my tribute of delight in return for their generosity. Through my bedroom window the dark blue sky with its sprinkling of stars coaxed pale shades of silver from the snow-covered garden and surrounding houses. The snow on the garden was pristine, except for a dotted line that ran across the centre from our house to the one opposite, like the perforations between two stamps seen from their white, shiny backs.
