Los post-its del señor Noestoy

There's a moving truck parked in front of Clàudia's building. A new neighbor is arriving! What does he look like? What does he do for a living? Why does he live alone? The enigmatic neighbor has arrived with a load of boxes of books, and Clàudia is determined to find out who he is. But it won't be easy. It seems like the neighbor is never home. After a week, all Clàudia knows is that he communicates with sticky notes. What's it like for someone who, in the age of cell phones, still sends little paper notes?
