“A lot of shock out there, you know. People didn’t think I could read, much less write.” — Former President George W. Bush touting his book “Decision Points” at Facebook’s headquarters in Palo Alto, Calif., on Monday. Bush went on to tell Facebook head Mark Zuckerberg that the reason he decided to visit the social network’s offices was, “cause you got a lot of people paying attention to us and I’m trying to sell books.”
