There's no new idea, is there?

As kids in South Wales at the end of the war, very little traffic came down our street until they introduced a bus every half hour. Between buses, we just had time to tie door knockers together across the street. It was very satisfying to watch the bus knock 48 doors. We couldn't get away with this more than once a year.

We thought we were very clever to devise this - now I find it came from Sussex!
