It’s been a long time since I last read it, but I remember thoroughly enjoying it as well. I had considered watching the movie, too, but decided to give it a pass after IMDB mentioned that it contained a graphic rape scene. I know that it’s related to the events of the book, but that was… you know… text. But it doesn’t sound like I was missing anything, either way.
It’s something I used to do, though I’m not sure when I started to do it or why. Interestingly, I broke the habit because I felt that doing so was reducing how much I actually retained by comparison to when I would read in silence.
Granted, I suppose it depends on your definition of “read aloud.” As I was sharing a space with people at the time, I’d have to whisper the words to myself than fully speak them out. But I don’t think there’s anything “insane” about it, either way. It’s good practice for when you find yourself actually having to read aloud.
