Mostly, I yell at Tom Nook, because he's evil incarnate. I owe him my soul! I also bitch out the lazy town residents all the time, and complain bitterly at the ones I hate who refuse to move out of my towns.

And yeah, it's a lot of yelling during fishing. Mostly for catching yet more Sea Bass and Crucian Carp, which I always call "Crucial Crap". Ha! I'm hilarious and oh-so-clever! XD
