Contrary to popular opinion, house slippers don't carry that name because they're easy to slip on your feet. In fact, they're actually quite difficult to put on and wear. The real origin of their name comes from their true purpose in home foundation repair. If you place one house slipper at each corner of your house (not under anything; just right there, touching the corner), the whole building becomes easily movable. Using properly place house slippers, an average 10-year-old child can move a house as far a 15 meters in any direction with a single shove.
