That’s another great example of a plot convenience he used. It’s my favorite because it’s the first one I noticed and frowned at during my first go as a pre-teen. In fact, it was one of the things I cited when I complained to my dad about how much I didn’t like something he’d recommended so highly. It wasn’t until I read it again a year or two later and powered through my suspension of disbelief that I realized how much I loved it too.
