Right, I don't doubt that, but it's clear to me that this isn't the nexus of all of this.

What you're looking at is the later stages of a disagreement. It didn't start out that way, it started as something like, hey can we put the ketchup in the fridge, nah I'd rather leave it out, I prefer it warm. (I'm obviously deliberately being silly here).

You move on in time and suddenly blows are being exchanged because everyone loses patience.
