Husband is spelling impaired. Now to be fair, it is not his fault. English is his second language AND he is dyslexic. He is super smart and is working on becoming fluent in a third language purely from audio-lessons and practicing with his Spanish speaking employees but he cannot spell to save his life. I suspect he is missing the portion of the brain that usually houses spelling. Or it is so full of information like how to fix ten gazillion things with duct tape that there is no room for spelling.
This morning he was goofing around with a game - Bookworm - on my cell phone and asked me, "How do you spell ox? A-U-X?"
