I am home. That is all.
And now you can do a survey of all homes built before the war and see how many have three conductor electrical systems. My Long Beach CA house had the original knob and tube wiring - no three-prong receptacles there! Many older building have unauthorized upgrades that install three-prong receptacles (to accommodate modern plugs), but only hook up the two power slots and leave the ground slot open!
(To get my computer equipment properly connected, I had to run a ground wire from a stake beside the water meter beneath the dining room window and under a ledge separating the room from the kitchen up to the wall outlet where it connected to the power line that fed the electronics.) Not even the garbage disposal had a ground!
When my roof leaked after the earthquake, water ran down the insulation coving the wires in the attic and filled up a bedoom lighting switch - noted when the lights stayed on even when the switch was off!
