So you did. I am a little anal about reading books, I guess, and I am always afraid I will "miss something" so I just continued. I've been sitting on the train mouthing all his labials and fricatives, and I do get a few looks now and then. I actually think this would be a great book to hear on tape because I was never sure if I was doing what I should with my tongue or uvula or whatever.
However, I will go to the signs and signification section. Sorry!
