Sorry, my comment was tongue in cheek. No offense intended.
I have seen fires in cars, HAD a fire in one car, heavily bunt wires in one truck and two cars.
Because of the butt loads of navy training, my mannerisms don't change a bit when I see a fire.
I remembered when my wife had her first stove fire, I casually walked over and mentioned "not bad", she did not think it was that funny.
I Will also mention to my dismay, I do not have fire extinguisher, cept water.
Another thing, I have cut live wire with Klein's twice, ran a screw through a bungle of wires once, cut through some with a skill saw, etc.
BTW, arc fault breakers are the BOMB, except when you want to run a major motor,(or should I say engine...tehe), including your vacuum.
