Swimming with Strangers

I remember reading “Familial Kindness” when it appeared in One Story. At the time I thought it was a bit of a puzzle, but it seems to fairly standard for Lunstrum's stories. I'm not a fan of clear resolutions, but these stories seem end ambiguously in a big way. That's not necessarily a bad thing, but for me is less than satisfying. I found motivations of characters to be something of a puzzle, as well. Not that they behaved improbably, just that within the story it wasn't always clear why they made the choices they did, and that seems important.
