Now you mention it Ginna is singing quietly to herself. Fascinating how quickly she can find rhymes.
Yes, many people would be unable to find rhymes quickly. What some people with dementia are able to do is impressive but we often fail to acknowledge this because the context is so bizarre. My wife has conversations with imaginary friends every day and, though she has an advantage in that some of the words are more like noises than words, the speed at which the 'dialogue' emerges is sometimes staggering.
We go to a memory cafe at which a guy who had been a theatrical agent used to sing pretty constantly ( and, it has to be said, not very tunefully) 'For all we know':
For all we know we may never meet again
Before you go make this moment sweet again
We won't say "good night" until the last minute
I'll hold out my hand and my heart will be in it
For all we know this may only be a dream
We come and go like a ripple on a stream
So love me tonight; tomorrow was made for some
Tomorrow may never come for all we know
So love me tonight; tomorrow was made for some
Tomorrow may never come for all we know
I cannot hear this song without thinking about him. I feel the song meant something profound for him.
