Touch that tells
This is the moment when a 100 year old woman, nearly blind and completely deaf, detects that her grandson is close to her - because he takes her hand and touches it to his beard. She knows that it is him because, among her descendants, only he has a beard.

Advanced old age has stolen two of her faculties - her sight and hearing, but she still has two faculties left - her sense of touch and the ability to associate the things that she touches with certain objects.
What is she thinking? Does she have a picture of him in her mind? If so, how old, how out-of-date is it? Is it 20 years out-of-date, 30 years out-of-date? Does she `see’ him as a young man rather than as the middle-aged man that he is?
If so, then her ability to associate touch with certain objects has failed her too. At least, as far as human being are concerned. Human beings grow old - they change shape. But she can’t see this different shape, she can only imagine what they look like now.
I was starting to get pretty depressed about getting old at the end of the last line. Let’s face it, most of us get depressed if we start thinking about - or writing about - getting old.
But that changed when I used the word `imagine’.
If she still has a sense of imagination, if she still has at least this faculty, does it really matter whether her perceptions are out-of-date? Does it really matter that she `sees’ a young man rather than a middle-aged man?
He’s still her grandson, he’s still part of her, she still has a sense of kinship with him.
It could just be that when we are old and infirm, and if we are nearly blind and completely deaf, our sense of imagination - if we still have it - will be a `must-have’ faculty, our last lifeline with the world around us.
And we won’t care if it’s out-of-date.
