Ooooh.
I was working on a weedeater (strimmer, if you’re a redcoat) when a very sadistic friend of mine noticed a puddle of gasoline on the ground and threw a lit match at the puddle.
The fire immediately raced over to me and into the fuel tank.
My instinct was to blow the fire out. That’s right, a fire, fueled by gasoline, in a plastic tank. I burned my entire face.
That erased the birthday candle instinct from my mind and I have been more careful since then when confronted with fire.
