Automatically I thought to myself, "I don't want to read about two animals doing it." I did a doubletake. "Hagrid's not an animal," I thought. And then I realized---part of the reason I don't like Hagrid is because I do think of him as an animal. He's so huge and hairy and coarse and trusting! He's like a really annoying, talking bear!
I don't like many animals. So it's only logical I don't like Hagrid.
