“Together: list the things we keep saying we'll do — then commit to one, with a date.”

A set-piece. One table, two pens, the same evening, one joint artefact. These are the pages people photograph.

Why this question

It doesn't have to be grand. The walk, the trip, the restaurant, the project.

And once you’ve both answered

Pick one before you turn the page, write the date beside it, and hold each other to it. The rest can stay on the list as honest fiction.

Answering it honestly

One table, two pens, the same evening. This one doesn't work by correspondence.
Argue about the details out loud before anything gets written down. The arguing is part of the artefact.
Finish in the sitting. A half-built set-piece has a way of staying half-built.

And the house rule, whatever the mode: leave a blank rather than write a lie. A blank can be filled later; a lie sits in the archive forever, and you both have to live with the paperwork.
