Several evenings ago I'm kicked back in my chair watching a James Bond movie and my 4 year old son is playing with his trains on the other side of the room. As the chase scenes get heated up with fast cars, pretty ladies, and guns blazing I find my 4 year old sitting in my lap watching it with me. He points out that they're shooting at the bad guys with guns like I have. Of course, this seems like an opportune time for another safety lesson about guns, shooting, etc. We cover many standard topics, one of which is "what do you do if you ever see or find a gun" and I repeatedly tell him you don't touch it, you tell mommy or daddy. He repeats after me, I confirm he understands, we cover it several more times, then other specifics about how and why guns are used and all is well.
A little bit later at the kitchen table he's telling his mom about the spy movie with fast cars and guns like daddy has. Feeling like a proud father, I say, "Tell Mommy what you do if you ever see or find a gun." and he quickly, loudly, and proudly exclaims, "SHOOT IT!!!"
Lesson learned: Never trust a 4 year old.
