Yesterday, I finished reading the fourth Harry Potter book to J. It’s been two decades since I first read the exploits of Harry, Hermione, Ron, and all the others. While I remember the gist of the story, many of the turns in the plot catch me by surprise once again. For example, when Harry (spoiler alert!) battles with Voldemort and their wands lock into each other, causing Harry’s dead parents to appear, I choked up, to the annoyance of J.
