Ten years ago we were caring for my Mother-in-law.
She had 'all her marbles' but with Arthritis and parkinsons was stuck in a chair, very frustrating for her.
A lot of her time was spent reliving the past, and as we took turns to stay with her I used the time away from home to go through her photo albums and make notes on who they all were, while the information was available.
I'm glad I did, some of the photos of my side of the family have to be guessed at (which curly blonde cousin was that?).
