Last night Bob came to bed with his baseball cap on so I asked him to
take off the hat.
He immediately started to take of his top.
One does not realize item by item, word by word , that is vanishing every
He had no idea what a hat was but a few days ago he had said the word.
So we do have to make sure when we make a declaration of a whole sentence
that most of it is lost.
One does not know for sure what the comprehension is about ANYTHING, what worked yesterday does not work today.
