Dear friends, I need your opinion; these are the walls of my 87-year-old mother's apartment, and we're worried they might crack. The house dates back to the 16th century, is on the second floor, and huge buses often pass on the main road. Do you think these cracks are normal, or should we be worried? My mother, too, is very grateful.
