Anki cards:
These small things may never change, so you shouldn't approach it with an "okay, I'll endure it" mindset. Better if you learn to view these things thru a different lens, such that they genuinely don't bother you anymore.
Or else – let them know. Or what do you think, does it sound like a good idea to keep enduring without ever saying? It'll explode later during some big conflict and they'll be like "why didn't you tell me earlier?"
Note that it doesn't need to be perfectly fixed or perfectly accepted. It's okay if your partner does little things that bother you, and you do little things that bother them, so long as the other knows it's a bother. Knowledge disarms it.
A tenet of NVC. I guess it's a version of the epistemic habit of avoiding premature generalization.
Instead of "careless husband", just observe that "he left toothpaste in the sink" and nothing more. By not attributing to fundamental traits (Fundamental attribution error), we leave ourselves room to understand their behavior.
