Ah, so the lad is just too inexperienced to know that you shouldn't wrap your hand around the trigger guard haphazardly. Sounds like responsible ownership. I am sure that lad will absolutely only handle weapons that have very likely (maybe) been cleared. This all makes it fine. Ok, fine, sure. That makes it all okay.

I live in Liberal Pacifist Nice People Land, and even my kids know that guns should be treated with the reverence they deserve. Only pointed at things you wish destroyed, finger never on the trigger unless it's time to end that target. I never let them handle a firearm until they were developed enough to understand those basic tenets.
