“But she is just better at it.”
Competence is not consent to permanent ownership.
Invisible labor is the noticing, planning, remembering, coordinating, anticipating, and following up required to make household life happen.
The person who performs the visible step is not necessarily the person carrying the responsibility.
If you ask someone to buy dog food after noticing it is low, remembering the brand, checking the budget, and sending the link, they completed a step. You still managed the system.
Competence is not consent to permanent ownership.
Completing assigned tasks is different from owning the outcome without supervision.
A minute repeated, anticipated, remembered, and coordinated 70 times is an operating system.
Requesting, explaining, scheduling, and following up are additional management work.

A fully owned responsibility has a person who notices, plans, does, and follows up without requiring a personalized household task briefing.
What tells the owner it is time to act?
What information is needed to act without asking you?
What outcome closes the task and the mental tab?
No. Chores are visible actions. Mental load includes anticipating, remembering, deciding, coordinating, and monitoring the actions.
The person responsible for noticing must continually scan for problems. That vigilance consumes attention even when no task is actively being performed.
Technology cannot replace a relationship conversation, but it can make work visible, provide shared context, assign true ownership, and remove repetitive reminders.
