I had been communicating with a new client for a few days before he politely pointed out that name was spelt Bret, not Brett.
Why am I telling you this? Surely as an editor I should be more observant, I hear you say. And surely I should be keeping this kind of oversight to myself. You’re probably right, but I couldn’t resist. It’s a perfect example of how the eye can see one thing and the brain can see another.
