He was lost, and wondering if it was far to the other end, and if his car could make it. I advised him to turn around as the puddles are still deep even after recent repairs.
I don't think he was lost, there's only one reason to have a toilet roll in your hand in a country lane. It was actually the waterboard van that made me think of Butterfly Lane as there's a reservoir part way along it and I though that was where he was.
