Case. One partner carries most of the domestic load and stores up resentment; the other genuinely doesn’t see a problem.
Model. Unbalanced load: one node runs at its limit, the other is under-utilized, and there’s no monitoring — the failure builds in silence.
Protocol. Make the invisible labor visible: list every task and redistribute honestly, rather than “helping”.
Lesson. “Helping” implies the home is one person’s zone. The home is a shared system.
