Another thing that drives me mad is that no one down south appears to close their curtains at night to go to sleep! The light would wake you up early! We have blackout blinds as well as curtains, I could not possibly go to sleep with no curtains closed for that reason and also that someone could look in (we live in a bungalow)! Is that the case?
I live down South ( London region), and everyone I know has their bedroom curtains or blinds closed.
I agree about the earlier post regarding the West End of Glasgow.. I was born and raised there, in a flat identical to the one in the painting, and I can't ever remember anyone closing their livingroom curtains or blinds at night, except if it was really cold and they wanted to keep the heat in.
We had roller blinds but I don't remember them ever being closed.
