The pen I used to make the mark is gone. Shouldn't make me nervous. Wouldn't, except that my room in the new flat is empty except for the mattress. I put the pen on the floor before I went out to think about what I need to do next over a coffee and when I came back it was gone. Such a small thing. Maybe it's nothing. I want to think it's nothing.
But I remember you saying that everytime you drew the mark in ink whatever you did it with dried up immediately afterward, even if it was brand new. Is it stupid of me to wonder?
