A little about my workplace. It is a big rectangular building on a hill. There are maybe, 10 floors? I can`t remember exactly. On my floor, the hallways are very nondescript. Grey / white floors and walls. Few signs or colours. But they are wide hallways and they stretch on for a very long time. My new game is to see how long I can walk with my eyes close. It seems to be a reflex to open them, to see how far I have walked or how much I`ve angled off from my intended straight line. Maybe by next winter I will be able to walk to the end without opening my eyes. This is practice for sleepwalking.
