A librarian appears on stage. He organizes books, and the books upset his life. To what extent, we wonder, is our hero a creation of himself and to what extent is he a product of his readings? The intermediary between the texts and the readers seeks his own identity in a lecture.

He will talk about the rain, or rather about what happens when it rains. "I have always been intrigued by the possibility of losing the thread of a speech and turning the presentation of ideas into a confession. To what degree do we control what we say? Like an actor, the speaker during a lecture can forget what he wanted to say or succumb to the temptation to reveal something awkward or catastrophic.

The Lecture on Rain arises from this peculiarly difficult circumstance. The librarian's rant is part of the long literary tradition of digression, that is, the art of pretending to deviate and talking about something else." Juan Villoro
