Your child fusses with his uniform for a few moments, then goes around to the back of the car to get his bag. You watch him walk away across the car park towards the school buildings. He looks back only once and gives a gesture that might be a wave. You rest your chin on the steering wheel and watch him in that bright, cool autumn morning with the leaves on the ground and you try to fix the moment in your mind. It occurs to you that in a few decades time, when they are both grown and the world has opened up to them and they are gone out into it, you’ll remember moments like this. And then you think: what will it feel like for you to have carried such memories over such a distance? And then you realise that you’ll also remember thinking about that too: the anticipation of an understanding not then available to you. Time is so strange. The child is gone and you drive away to your work and the world’s new day.
