They are one of my biggest fears. My grandparents lost everything to a fire when I was a kid. It made an impression on me, for sure.
My aunt and her kids lost their house one Christmas (they were with us at the time so fortunately not at home). House fires are so destructive!
My dad always unplugged appliances and was generally drilling the fear of fire into our heads when I was a kid. He never said he’d been through one but that was always his thing.
