Two rooms covering 28 square metres, built for two things. Between them they now carry eight uses. Two of the two carry more than one, and living room carries five. The median room is in use 9.5 of the 16 waking hours. The two rooms whose use is decided by somebody else's calendar.

Fourteen collisions, each one use taking a room another use was already in, at a median of 37.5 minutes. They fell ten by the interruptible job and four by the scheduled job. Six of them happened in the kitchen. Fourteen of the forty-seven, ten absorbed by the interruptible job and four by the scheduled one.
Two people live in this flat and both work in it. Between them they absorbed forty-seven collisions in fourteen days.
Thirty-one fell on one of them.
The number, and what it is not
Sixty-six per cent against thirty-four. In a household of two, where every collision is one person giving way to another, that is a substantial imbalance and it held steady across the whole fortnight — the split in week one was sixteen to seven, in week two fifteen to nine.
It is not an imbalance in effort, consideration or willingness. Nothing in the log or in either person's account suggests anybody was being inconsiderate, and both describe the arrangement as sensible.
It is an imbalance in who moves, and it is produced by one fact.
Thirty-four against nine
One of the two jobs had thirty-four scheduled calls over the fortnight. The other had nine.
A scheduled call is the only activity in this dwelling that cannot be moved, cannot be quiet-adjacent, and is witnessed by people outside the household. When one is due, the quiet room is needed; if the quiet room is taken, another room is needed; and whatever was in that room leaves.
Twenty-two of the forty-seven collisions involve a call directly. The remaining twenty-five do not, and they still fall the same way, for a second-order reason: the interruptible job spends its day in rooms it was pushed into, and rooms it was pushed into belong to other activities at other hours.
The rate, not just the total
The clearest way to see that this is about the work rather than the people is to look at how often each job gave way when it had the chance.
| job A | job B | |
|---|---|---|
| scheduled calls in fortnight | 9 | 34 |
| collisions where it gave way | 31 | 16 |
| rooms it occupied over the fortnight | 3 | 1 |
| collisions per scheduled commitment | 3.4 | 0.5 |
The bottom row is the one that does the work. Per external commitment, the interruptible job gave way nearly seven times as often — which is what you would expect if the number of commitments is what determines who moves.
Why "interruptible" is the right word
Not "less important", which is the reading to avoid and the one the household itself was careful about.
Both jobs are full-time, both are paid, and neither person regards either as subordinate. What differs is the shape of the commitments: one job is organised around appointments with other people, the other around work that has to be finished by a date.
A job organised around dates can be done at any hour. A job organised around appointments can only be done at the appointed hours. The first can absorb a displacement by moving; the second cannot absorb one at all.
The question is not whose work matters more. It is whose work has somebody outside the building waiting for it at a stated time.
What this predicts elsewhere
Any household with two workers and one quiet room will distribute collisions by the same rule, and the rule has nothing to do with seniority, pay or anybody's view of whose job is more demanding.
It will fall on whoever has fewer externally scheduled commitments. That might be the person who earns more. It might be the person everybody in the household regards as busier. The distribution is set by calendars rather than by any of that, and because it is set by calendars, it is invisible to the conversations households actually have about fairness.
The split by week, and by room
Week one: sixteen to ten. Week two: fifteen to six.
The imbalance is larger in the second week, which is the week the two changes were made — and both changes removed collisions that fell on the interruptible job, which is why the total came down and the proportion went up.
That is the clearest statement of what furniture does. The folding table and the moved exercise took five collisions off the person who was already absorbing most of them, and left the ratio worse than they found it.
| room | fell on A | fell on B |
|---|---|---|
| kitchen | 15 | 6 |
| living room | 10 | 4 |
| bedroom one | 4 | 4 |
| bedroom two | 1 | 2 |
| hall | 1 | 0 |
Bedroom one is the only room where it is even, and bedroom two is the only room where it leans the other way — which is what you would expect of a room that belongs to one job and is occasionally entered by the other.
What the person absorbing them said
Asked at the end of the fortnight whether the distribution bothered them, the answer was no, and the reason given was not resignation.
It is not that I mind moving. It is that I did not know I was doing it that often.
Thirty-one displacements over fourteen days is between two and three a day, each lasting about half an hour, none of them significant on its own. Nobody experiences that as a pattern while it is happening. It becomes a pattern when somebody writes it down.
That is the entire practical value of the count, and it is why this site's recommendation is three days of logging rather than any particular change.
