Like the tide, it comes in and it washes over the beach. It's beautiful. But like the tide it goes out, sometimes it goes out further than it ever has, it recedes back across the beach and further out beyond the horizon. The bare seabed opens up in front of you and all you can do is look at it.

The slug lives in my bathroom. I only see it in the early hours of the morning, when I'm not quite right.
