Most days he is struggling to make himself understood. Both the syntax and semantics of language is eluding him. For one of the masters of language and vocabulary to struggle is unbelievably difficult to watch. I don't always know what he is trying to tell me. I usually resort to having him show me what he means and we work through it that way. "The bed won't turn off" really means that a lamp by the bed is on and he doesn't know how to shut it off.
