It would appear that Ernest Bywater and I are both in process of a story about a runaway, both titled "Runaway"βthough mine with the article "the" beforehand, and his with an exclamation point following.
I'm amused, because I know I started writing mine before hearing of his, and I assume he was the same. But we still ended up with similar titles, though it seems to be drastically different premises.
I know these sorts of coincidences happen all the time in publishing and film and other arts, where a couple of people independently all suddenly seem to create things that bear strange similarities to each other. I've just never to my knowledge been part of that before.
Coincidences are fun!
