How do you make sure that when you wake up at midnight to go to kitchen or washroom, you don’t make any mistake at all that might cause anyone to wake up ?
p.s. While being a guest, I really dislike the screaming (screeeeeeching) sound of any old door that has not been oiled for centuries…the sound of which might not be as prominent during the noisy time of the day to make people jump from their bed at night.
