Memory

According to Douglas Adams the constant repetition of the anecdote describing the inspirational moment when he formulated the title of the ‘Hitchhiker’s Guide to the Galaxy’ had obliterated his memory of the actual event.

I agree; a story often re-told eventually becomes a memory of the telling and not the doing.

Similarly a story remembered through the lens of a single photo has only one snatched moment where the story has achance of matching any version of what really happened.
