When I was a kid my father took me out to the desert and I shot watermelons and gallon water bottles with a shotgun.
The experience was designed to shock and scare me into the realities of pulling the trigger. It worked on me. I had a shotgun in my closet from the age of 13 on (my father taught me how to shoot skeet). I never pointed at anyone.
Once a kid discovers that it is not a movie… The violence of sending a round down range. The bang… the kick… it usually snaps it into prepective…
