Ten days ago, I expressed an idea stuck in my head thusly: P.S. (but no more) scribed and scribbled, mars the end of your letter home Then I asked people to join in with their own variations on this theme.

An image / idea has lodged itself in my head and won't leave, so I've decided to explore it further and ask for your help. The image involves a letter home with a P.S. at the end, but nothing after it.
