I am a reference.

I really like this response, because it reminds of a story about J.R.R. Tolkien:

He received a letter that criticized his spelling of the plural form of the word 'dwarf.' He had spelled it 'dwarves,' instead of the OED (Oxford English Dictionary) approved spelling 'dwarfs.' Tolkien responded to the letter by saying that he had changed his mind since writing that entry in the dictionary!

There's a similar story about a Yale law professor who was arguing a case in the US Supreme Court, and one of his former students, who was then a Justice (Byron White, I believe) said, teasing him, "Counsel, you realize the experts in the field disagree with your position." And the professor responded, "Yes, but I've changed my mind."
