Too tired for this shit...

Tonight I felt like starting a new book. It's been a week or so since I finished Catcher in the Rye, so it was time. I was feeling some crazy ass sci-fi adventure like Dune or Ender's Game. Something really far out. Instead I grab "Sophie's World" a book about the history of philosophy that I bought right before school started. So far the book is out of control. I'm only 20/470 pages in so far, and honestly I don't know if I should keep going. I'm not spoiling much by saying this I don't think, but it seriously went from page 16 to 465. What. The. Fuck. No continuity either, just picking up the story where I assume it would be at on page 465. I flipped forward a little more and see it goes back to normal page numbering in a little while, but Jesus, what gives?
