I think some people use the alphabet to choose the letters to make the word? Or simply pointing to either YES or NO to straightforward questions?
Any tips or suggestions would be gratefully received.
Saw the neurologist today, when asked how things were, I told him to think of his worst day and then magnify it a thousand times and then perhaps he could begin to imagine how "things were".
think he was somewhat taken aback as they always expect us British to say, "oh, mustn't grumble"!
