Everything was normal and as it should be until one day I woke up and there was something wrong. I didn't know what it was, but it was a kind of persistent thing that I couldn't quite ignore. Something was cold and it was inside, not outside. It was like a place where someone had poked me with an icicle. A splinter of winter. The days passed like they do and I just got colder. The cold spread until I was like a sculpture of ice. I didn't sneeze any more, and I couldn't cry and if I tried to come it was like a tendril of porcelain. I was a solid man. You could throw rocks at me and it didn't hurt at all. I just splintered a little.
Perhaps fortunately, no-one noticed and everything carried on being normal and as it should be, all around me. But I was frozen.
