I agree about the sound on Ludwig - thought it was me because I watch on the laptop! I often have subtitles on too, it helps me concentrate. Love Agatha Christie too, I think my favourites are the radio adaptations of Poirot.
Hope you can have a rest today @MewithME but I totally get the lonely and boring feeling.
I'm a bit discombobulated - woke up before 6, got up and had breakfast and went back to bed, thought I might briefly doze, and then I woke up again about half an hour ago. Got my breathing class shortly then no other plans for the day, although I should have a tidy up.
