And so is your response, which clearly stems from the level of 'care' which truly matters.
One of the really meaningful compensations that one finds in spending a lot of time in the Care Home, is that of observing behaviour which quite clearly reflects a need for and so often finds expression, in what could be seen as inappropriate or even infantile - cuddly toys, or dolls. There was a time when these things were not encouraged, probably at the same time as Carers were encouraged to 'bring back' residents with dementia, into the present world. Thankfully, that has changed. Dementia world is deep, very deep and goes beyond even the most introspective analysis of brain and all of that entire neurological research - all of which is really superb in its own right and fascinating. But when you see someone genuinely in distress and I mean distress, owing to having lost a tissue on which was written a single word - a word so very important to that person - or someone else who finds absolute comfort in their 'dog', a wonderfully fashioned life-size dog, with soft 'fur' and sparkling glass eyes and who 'talks' to that dog just like it was alive - or someone who takes an item and hugs it throughout the day, like some surrogate comforter - then you do respect 'comfort' in that context. This is why Care is so very challenging, even for those who continuously practice their 'dementia' skills.
The song you so thoughtfully wrote for the lady who flops into her chair, is an example of that 'care' and it matters, it matters a very great deal. So, you warrant respect and most certainly a very big 'thank you' for doing just that.
