Mainly, my father, his work was to do with safety and he applied it to his home as well.
Cold before hot water in a sink etc, always turn pan handles towards the worktops, DH often forgets that one with dire results.
The one that kept me going was,' The man who never made a mistake, never made anything".
My mother was the clean underwear one, I still can't wear anything twice. Once when on holiday we realised I had forgotten DDs knickers. They had listened to granny as well, I had to go into a very old-fashioned Drapery shop in Scotland and ask for 14 pairs of knickers, which were promptly binned when we got home.
