From reading the book up to Chapter 3 I definitely had some mixed feelings. The book starts off with Calvino placing you as the main character right away. He does this in a sense that makes it fee like the author is narrating how you are about to read this book. Then the book jumps right into a story at which this point I feel I was involved and part of the train station setting right there with the narrator.
I thought this was a very clever technique Calvino used so far. The author created one story using the reader as the main character and has them dive right into a story from which it almost seems to come to life. This is a little confusing because it does jump around a little bit but after reading up the the third chapter, I can sort of realize what is going on.
