Stop being the teacher.

It is not fine. It means: I have asked before, it did not stick, and asking again costs me more than doing it myself. The task is small. Being the only one tracking it is not.

The lesson on ownership. The difference between doing a task and owning it — holding the noticing and the remembering, not the work at the end.

Asking repeatedly with no change costs more than silence. So the asking stops.

The asking is the work. Being the person who assigns, reminds and checks is a second job, invisible precisely because it produces nothing anyone can point at.

The lesson on cognitive labor. Why a fairly split chore list can still leave one person exhausted.

Cognitive household labor, the planning and the remembering, is split far more unevenly than the visible tasks are.

Because remembering was never assigned — it was assumed. Nobody agreed you would hold the household calendar in your head. It arrived by default and stayed.

The lesson on default assignment. How the household’s memory ends up in one person, and how to hand a piece of it over for good.

Mothers handle 71% of household mental-load tasks against fathers’ 45% — and fathers are more likely to believe the load is shared equally.

Two words that mean different things in different weeks. In the weeks before a period, mood swings, irritability, tiredness, poor sleep and appetite changes are all common — the NHS lists every one of them. The same small annoyance genuinely lands harder, and being told you’re overreacting is its own separate injury.

The lesson on the weeks before. What actually changes, so it can be planned around instead of argued about.

PMS is the name for the symptoms many people get in the weeks before a period. Tiredness, irritability and mood swings are among the most common.

Sometimes literal exhaustion. But heavy periods are one of the most common causes of iron deficiency anaemia, and that produces exactly this — tiredness, no energy, breathless on the stairs. It is easy to live alongside for years without anyone joining the two things up.

The lesson on iron. Why this gets normalised for so long, and the blood test worth asking for.

Heavy periods and pregnancy are very common causes of iron deficiency anaemia, whose main symptoms are tiredness and lack of energy.

Not about him, and usually not about desire. Being touched all day and carrying the household’s running list draw on the same finite thing. And for a lot of people desire doesn’t arrive first — it arrives after closeness, not before it.

The lesson on responsive desire. Why wanting-after is a normal pattern rather than a fault, and what makes room for it.

Basson’s model of female sexual response describes desire that is responsive — arising after intimacy and arousal rather than spontaneously before them.

You are not counting to win. You are showing evidence, because the first two times left no trace and you are tired of being told it isn’t that bad.

The lesson on the evidence problem. Why one partner keeps a ledger and the other genuinely does not remember.

Parents tend to overestimate their own contribution, fathers more than mothers — which is why the same week gets remembered two different ways.

Not permission. It is the sound of someone who has stopped expecting to be consulted and decided the negotiation costs more than the outcome is worth.

The lesson on withdrawal. How preferences go quiet, and what makes them safe to state again.

A preference that never changes an outcome stops being worth stating. That isn’t sulking, it’s arithmetic.

Often true, and nothing to do with your partner. Endometriosis takes a long time to diagnose, and on the way there its symptoms get mistaken for IBS, fibroids and pelvic inflammatory disease.

The lesson on being believed. The two questions that move an appointment from reassurance to investigation.

The NHS states plainly that it can take a long time to diagnose endometriosis, and that its symptoms overlap with several other conditions.

Sometimes that’s right. Often it is where the investigation stopped. Women’s pain is more likely to be treated as psychological and referred on to talking therapy rather than investigated further — that is documented, not a feeling.

The lesson on the one question. “What would we be looking for if it isn’t stress?” — and why it reopens the conversation.

The IASP reports that women’s pain is “more psychologized, mistrusted and judged as unreliable”, with more referrals to psychological treatment and less effective pain relief.
