Like a lot of people with Dyslexia, he thought he had it down (he apparently memorizes everything he says at events like this--and consequently doesn't do them often). But when memory failed, he went to the prompter and read what he saw. I agree about the earpiece, and I suspect he will never appear without one again. But as Dyslexia is a hot-button topic in his religion, I wonder if he will ever address this in a conventional way.
