Yeah, you can't miss with a shotgun. That was one.
And you don't need anyone to show or teach you how to shoot a shotgun. After all, you can't miss with it, right? So all you gotta do is keep one in your closet and you'll be able to kill anything that tries to climb in the window.
And, of course, you don't need to keep a shotgun loaded, because racking it makes a noise that causes intruders to crap their pants and run away crying for their mommas.
Plus, a 12 guage won't punch through any of the walls inside your home, no matter how thin the walls are or what ammo you use.
Had some trouble learning the various calibers. After all, the 9mm, 9x19, 9mm luger, 9mm largo, 9x18, 9mm steyr, 9mm short, 9mm parabellum ... you know, they all sounded pretty much alike to me! Plus, whenever anyone would start to explain 'em, they'd start with some basic little tidbit ("That's a 9mm") and then quickly add a whole bunch of extraneous stuff, up to and including summaries of all the caliber wars that have ever been fought, and with interesting little rabbit trails about which companies developed the round and why they developed it and why the FBI isn't using it anymore or has gone back to it or stopped using it again and why it's better than a .45 (or why nothing is better than a .45) and which guns it goes in and why it doesn't work so well in one of the guns that it was designed for and what weight of bullet you'd expect it to propel and why they've stopped making it and how much 'stopping power' it's supposed to have and which companies used to make it and don't anymore and which companies make it now but are rumored to be about to discontinue it and which new guns are going to be coming out which shoot it and by that time my eyes would be glazed over and I'd think, "I am never going to get the hang of this!"
Another misconception. I thought I wasn't good enough to take a class. (Hmmm, something wrong with the logic there -- ya think?)
I'm sure there's more ...
