Some days in the wild Western Isles are days when the only thing to do is curl up tightly and twitch. If you should come a-knocking on Lewis’s front door on such a day, and nobody answers, it’s because we’re all at home, curled up tightly and twitching. Check the sky. It will probably have clouds that look like God has just revoltingly added extra milk to his already o’er-milky tea. Check your expensive mainland shoes. They will probably be partially submerged in puddle and doom. There will be no movement behind our curtains, and there will be no light in any window. Traditionally, we twitch in the dark. You should turn around immediately and return some other day.
