It was draughty.

       I lay in bed last night thinking it was "a bit draughty" purely from sound. Awoke this a.m. to find that the wind had permanently "disconnected" the Lantern from its lead, and disassembled the "Box" ball/Globe and whisked it away onto the Lawn.
       I've also noticed that the Greenhouse opening window is now permanently open until I either find & replace it or buy a bit to fit .
