And those clever people who live inside the computer have used their digital imagination to spin a spell of zeros and ones. To show us how someone might now look - if we turned a corner and found them back from the dead, standing, smiling in a patch of sunlight, dug up from the bottom of the lost property box.
It’s a game we can all play with our missing. It’s make believe and re-draw the picture how it might have been. It’s fold the corners and crumple the edges, fade the colours and bruise belief. It’s smudge the smile and place coffee cup rings around the eyes.
And however well you play, it all turns out the same - a thumbnail image of someone you never knew - who day by day grows to look a lot like you.
