The library has been closed for half an hour and Rosario, the librarian, is setting the last few books on the shelfs and erasing the underlining that Armando, a waiter at the university’s café, has scribbled in several novels. That is, until she discovers that they are not simple underlines and that they haven’t in fact been written by Armando. When she looks up, she finds Armando standing in front of her.
