People argue about everything from sports to politics all the time without ending up dead, so you gotta wonder about a story about a guy getting shot over a garden hose, even where two hostile parties are concerned. What's sillier about a garden hose argument than sports or politics? There's not many things people argue about that aren't silly, and yet people still argue in 2019.
The guy is gonna get himself shot over his willful ignorance and arguments about hoses, appliances, tools, supplies, and junk around the house, he talks too fuckin much to be around a true gangster, the kind of guy who will kill a motherfucker and his dog for talking about a garden hose.
The guy and his brother in law were laying in the grass like two rotten pieces of Swiss cheese after their argument over the garden hose and the shooting that followed. It turned out they were both right about each other, and tomorrow didn't need either one of them any more than today did.
