A woman came to the desk, looking slightly lost. She said "I've tried to look this up in the catalog, but maybe I'm spelling his name wrong? It's a dog trainer. Cesar something..."
As you might imagine, from reading my blog, I flinched a bit. But, I looked him up, and explained that the name wasn't spelled like "Julius Caesar". I gave her a piece of paper with the call number, took a breath, and said "That's where you'll find his books, but may I make a few suggestions? I find his methods to be more coercive than strictly necessary, especially depending on the breed you're interested in. I have a Doberman, and they're just so smart, that kind of thing isn't necessary, and might backfire."
