This has always struck me as the most dangerous place to live. You build your house at the foot of a big stack of stones on the edge of a quarry, right next to a very angry ocean. It just can’t be a good idea.

This is what can happen to stones – and manmade structures – when the ocean in question has a snit. This is supposed to be a long, elegant harbour wall. Note carefully how it appears to have been eaten by a giant puppy.
