• http://mislav.uniqpath.com/poignant-guide/book/chapter-2.html
• This chapter looks a scene setting or an concensus process between the author and readers. The chapter contains little information about Ruby itself.
• In a nutshell, important information in the chapter as an introductory book for Ruby is:
1. At first sight, the author thought Ruby was meaningless. But later they clicked. (That can happen to you as well.)
2. By learning Ruby, you may be able to improve your brain performance.
3. Using Ruby costs nothing.
4. Enjoy cartoons with foxes.
