I need you to solve a debate that is make or break for my marriage.
Skylar, who is wrong, thinks it's rude when I'm working or writing and he starts trying to talk to me and I very politely ignore him completely. He also thinks it's rude when I mindlessly respond with a curt "uh-uh" without ever looking at him.
Obviously he, who is wrong, would characterize this differently than I have. He would incorrectly tell you that I'm not "politely" ignoring him and that the fact that I'm ignoring him is inherently impolite, but nonetheless, I'm not doing it "politely" anyway. He would falsely say that all he's doing is trying to treasure the few seconds we have together, which his horrid schedule barely and rarely deigns to allow, and that my refusal to join him in that honorable quest in fact makes me quite rude.
Then I'd interrupt at this point (but I'd do it politely, obviously) and I'd say "no one made you go learn how to put cameras up people's butts and look at poop through a microscope" and he'd cut me off there and yell "for the last time, that is not what I do all day." And then I'd remind him that it's rude to yell and interrupt so maybe a little self-reflection would be a better use of his time than this current escapade of projection.
He'd roll his eyes at that point and say it's "useless" arguing with me, which is curious, because he would then continue to argue with me. And look, I'd suggest that if you're doing something you think is useless, that probably says a lot more about you than it ever could about me.
