Oh wow. That reminds me of the time I used to rent a Troubadour harp from a high school. I used to keep the harp in my bedroom where I covered it up for the night. One time, during the first days of having that harp, I woke up in the morning to uncover the harp only to find a broken string plaguing the harp. It must have broke in the middle of the night when I was sleeping and I didn’t hear a thing. Must have been a heavy sleeper back then. Otherwise, I would’ve woken up to the sound of the string breaking off.
