There was a famous children's story author who wrote 2 books. The first was from the POV of a kid continually being bothered by a bully. The second was the same story, from the POV of the bully. But I never read them. Wish I could remember the titles or author name.

I read those, about 30 years ago. I don't remember the titles or author, but I do remember being surprised by the bully's POV and feeling empathy for him.
