Some people hold the belief that if an upside-down shoe or slipper is not turned right side up, it ruins things, causes fights in the house, makes things go wrong, etc., therefore, it should be turned right side up as soon as possible. Holding this belief is absolutely wrong; however, keeping any object in its proper (original) position falls within the bounds of manners and etiquette. (Aham Masail / Vol: 2 / Pg: 33)
