I realised I made a big error but treating elderly people as a different group, with all this about compassion and putting myself on their shoes.
So, retract myself from these words.

The only fact to call “kid” an elderly person is very insulting. How this person could feel if (s)he hear it, this person who should be value for how long (s)he lives and the wisdom accumulated.
I have been thinking what we call an increase of stubborness could be explained because of our prejudices and when we to try them to do what we see more convenient for us and their understandable reluctant to do it and depend on certain things on others.
I want to rectify.
My father was stubborn always so he continued being the same. But there were many traits that I discovered as a personal development.
He became more understanding, sensitive, fun, smart, to name ones.

My grandmother, ones she was cared and medicated, she was such a reasonable person. Calmer and as she was always an open person.
