The person who gets the final edit can become the official owner of a shared memory.

Whoever writes the last version of a story ends up owning it. The others were there, remembered it differently, and simply did not get to the page, so their version stays private while one account becomes the account. This is rarely dishonest; it happens through ordinary tidying and the smoothing that makes a story tellable. Over years, the tidy version quietly replaces what people recall.

If you write the recap or caption the photographs, leave room for the others inside it. Ask one person what they remember before you settle the wording. And if a shared story has stopped matching yours, you are allowed to say your part aloud.
