Bad stuff happens on the fire line,
You think you're in mop up mode,
All of a sudden you're at the head of the fire.
Nothing is a sure thing.
You listen to that voice,
Feel your throat going dry,
Your bowels tightening up.
When things happen they happen fast.
Sometimes they’re over before you know anything.
