LPT: When propping open a door, do not jam an object in by the hinges.
Often I see movers and contractors do this by sticking a rock or a tool in the door at the hinge. This puts a lot of stress on the hinge and often bends it or pulls out the screws. When this happens, the door gets out of alignment and no longer closes properly.
Instead use a doorstop or prop near the handle side of the door to put less stress on the hinge. #entertainment
