On a side note, I got a bit excited too when the author talked about starting a children's literature reading group after finding a kindred spirit. She had debated about whether to bring up the fact that she liked Harry Potter, as it seemed shallow to like children's lit, especially when one was speaking to a literary agent. Lo and behold, she later found out that the literary agent was equally fond of Harry Potter. She later added this quote from CS Lewis's "on three ways for writing for children":
When I was 10, I read fairy tales in secret and would have been ashamed if I had been found doing so. Now that I am fifty, I read them openly. When I became a man I put away childish things, including the fear of childishness and the desire to be very grown up.
I had read this excerpt in an article by brainpickings. I guess perhaps we shouldn't be afraid of being judged for what we like. We like what we like.
