A certain inevitability

A strange man just came to the door. He had a dog on a lead with him. I thought, 'That dog looks just like George.'

It was George.

We hadn't even noticed he'd gone walkabout. And we don't know how he got out.

And the strange man wasn't a strange man at all but the son of my friend across the road. He used to be Elder Son's best friend but we haven't seen him for years as he's been living away.
