If you look at everything with such a cynical and high and mighty attitude you must live a bland life. It's funny. If he was teaching her gun safety and it was her 1st time holding a gun, there probably was not any ammunition around. I know when I show my GF a new gun, I make sure she can operate it and dry fire it with no ammo in it before I give her a loaded gun.
Everyone I know that are gun owners found this to be extremely funny.
I say she did alright, she didn't throw the gun, she put it down on the table before running off.
