Intent and impact
Forgetting a request may not mean it was unimportant. Interrupting may come from fear of losing a thought rather than lack of respect. But good intentions do not erase impact either. Both things can be true at once.
Move the system out of memory
Shared calendars, written plans and agreed homes for information can reduce the number of relationship problems that are actually memory-management problems wearing a disguise.
Talk about the pattern, not the person
“We keep losing track of household jobs” creates a problem both people can solve. “You never care enough to remember” turns the same problem into a judgement. Clear expectations and specific requests are usually more useful than mind-reading.
