Our time has come. Some call it spite, I call it karma.
The front neighbours house is officially on the market (there’s a dirty great big sign on their freshly painted front fence), so all you good people start thinking seriously of harmless yet annoying things to drive them mad over the open days/auctions/time remaining for them here.
All things suggested that are this side of legal (no matter how close to the line) will probably be acted upon.
