It had been a week since my colleague stopped coming to work without leave. When I went to his place to check on him, I found him lying on his bed hiding under covers. I asked what was wrong, and he replied, "That woman over there says I mustn't go out." I looked at the place he pointed. Then I saw in the narrow gap only a few centimetres wide between the fridge and the wall, a long-haired, paper-thin woman staring at us.
