I showed this video to our younger son and he said "So that's what that sound is! I spent all last night peering out into the dark of the garden wondering what that eerie noise was."
Talking of youngest son, he and our elder son have travelled to Bristol today to buy something for a new business venture they are embarking on. They phoned me on the way home both telling me all the news on loudspeaker. I could barely make it all out they were laughing so much about funny tales that had happened. It had all gone so well, I was really lifted by their enthusiasm. I think there are some fun days ahead for them!
