Lives are snowflakes - unique in detail, forming patterns we have seen before, but as like one another as peas in a pod (and have you ever looked at peas in a pod? I mean, really at them? There's not a chance you'd mistake one for another, after a minute's close inspection.)
Far off down the road, through the lazily drifting snowflakes, they could hear the merry sound of sleigh bells. Their gay little tinkling flying ahead of the sleigh and lighting up the night with sparks.
