You have with you the book you were reading in the cafe, which you are eager to continue, so that you can then hand it on to her, to communicate again with her through the channel dug by others' words, which, as they are uttered by an alien voice, by the voice of that silent nobody made of ink and typographical spacing, can become yours and hers, a language, a code between the two of you, a means to exchange signals and recognize each other.
Well, we think that time "passes," flows past us, but what if it is we who move forward, from past to future, always discovering the new? It would be a little like reading a book, you see. The book is all there, all at once, between its covers. But if you want to read the story and understand it, you must begin with the first page, and go forward, always in order. So the universe would be a very great book, and we would be very small readers.
