Even my mother said this was seen a silly when she was little.
“We used to have drills in school where we would have to dive under tables when the bell went off. much good that would do us when a nuclear bomb goes off ”
“Another one we were told was to place a mattress against the door.”
^_^ 28:00 is my favorite : when you hear a nuclear bomb alarm and your not near a house or bridge jump in the nearest ditch and cover your head.
XD Build a fort out of tables that’s bound to save you!
