A fair division of objects may still leave an unfair division of inconvenience.

Splitting the visible things evenly can conceal a lopsided split of everything else. One person gets the object and the maintenance, the trips, the phone calls, the mental load of remembering; the ledger looks balanced and the days do not. Inconvenience is harder to count than possessions, so it tends to go uncounted.

When you are dividing anything, at home or at work, list the ongoing costs alongside the items. Who will actually be doing the follow-up. Ask the question out loud rather than assuming it will sort itself out, because arrangements that seem fair on the day quietly become unfair over the following year.
