This dad really wanted to show off. He brought out his gun for the photo opp, which I think is pretty incredible. I'm sure this was taken in a state where guns are common, but I'd still be very nervous if I was that boy. It's hard to tell if his smile is genuine excitement or fear. I'm sure that girl got home by curfew without any problems.
I'm sure it's hard as a father not to stunt on your daughter's date. It's part of the fun of having a daughter going to prom. It's all different if you have a son. You don't get to have that kind of fun. Don't try to threaten your son's date. It won't go well. Another dad will show up on your doorstep with his own camo rifle.
