Damn, I can't even imagine how hard that job can be at times. Good on you, Fletch. Takes a special kind of person to do that and help others. Hope you're still able to shake it off at the end of the shift.
It's something I've thought about before- how traumatized we are as a nation and how it must manifest itself in ways we don't even know. You hear stories all the time of war veterans being triggered by fireworks, and God knows it scares our poor pets (which always pisses me off). I live right off a major highway and intersection, so I've heard all manners of loud-ass car mufflers backfiring, and I often see people have that moment of panic cross them, and not just from being surprised at a loud, sudden noise. I'd like to think I'd recognize the sound of gunfire, but I don't honestly know, and I hope I'm never in the situation that I'd have to identify it quickly. I suppose maybe it depends on the type of gun, how much it sounds like fireworks.
