Your Lordship
I had the same problem last night. Betty is a problem to sleep with...and she does get around at this time of year!
Last night (in London) I slept with the window open and no cover whatsoever on the bed. Actually, no cover on me, either!
Tonight, I'm in Tirana, Albania - you'd expect it to be warmer but it's been raining hard!
Good luck with the unusual weather.
