some things change so fast there's hardly time to notice. i love the word supple but often things are not that way. my back, my teeth. some things erode for years and we push our awareness below the threshold. i note supple things but i may not get to touch them, or only with my eyes. some things i make note of just before or after they go beyond. still, my back has been more or less supple and will be again, though my teeth won't come back. i ate too much fantastic candy as a kid.
