Remove all the furniture, and spray the floor with a hardwood flooring cleaner or your own mix of 10 parts water to 1 part white vinegar. Gently wipe the floor with a terry-cloth mop or a towel wrapped around a mop head. Close the windows and doors to keep dust contained in the room you're sanding. About $200.
Upside Down Flag. Flying the American flag upside down is an officially recognized signal of distress. Here is the relevant part of the US Code of Laws regarding how to fly the flag when in distress: THE UNITED STATES FLAG CODE Title 4, Chapter 1.
Above other flags - Hang the flag above any other flag on the same pole. Other flags, separate poles - Hang all flags on equal poles. Hang the U.S. flag on its own right, hoist it first and lower it last. In a window - Hang the flag vertically with the stars to the left of anyone looking at it from the street. Half-mast - This is a sign of mourning. Raise the flag to the top of the pole then lower it to the half way point.
