Oh god, I've been thinking of this little boy all last night and today at work.
My own son, when he was 4, ran away on the way home from school, through the woods and straight down the road. He was so fast and despite my shouting, he did not stop and got all the way home, usually a five minute walk.
I was sprinting after him, he was so bloody fast. After that experience, I taught him how to walk sensibly, where to stop, how far he could go from me and when to hold my hand. We have, fortunately, never had an issue since. However, my son doesn't have autism and can hear perfectly well.
My parents look after him a lot and I know they wouldn't outrun him.
This poor little guy his poor parents and his grandad. I can't stop thinking about how he must feel. How on earth do they get through this?
