The yearly review of the M. family vault concluded on Thursday that the family it was built for no longer entirely exists — having since acquired a second child, a Labrador, and a new state of legal residence.

The vault, drawn up two years ago for a family of three in one state, now serves a family of four in another — a discrepancy the review flagged with the patience of an accountant and the quiet dread of a parent.

The dog, the review confirmed, has no role in the vault and is not expected to acquire one. The new state, however, changes the legal picture; the new child changes the plan. Both had gone, until Thursday, entirely unaddressed.

The vault was perfect for a family that has, in the meantime, quietly moved on.
