Well, there is the (very) occasional funny side, even if it's of the black humour variety.
My dh would sometimes come with me to visit. He had always been a 'golden boy' to my mother, so she had usually been very pleased to see him.
By this occasion she was past making any sort of meaningful conversation, said very little, and even when she did, it was usually very hard to make out what she meant.
As usual, I had taken chocolate - a bar of Aero, reasonably soft to eat. I gave her a piece, then gave a piece to Dh.
My mother turned to me and said very crossly, clear as a bell, 'i could have had that!'
She then turned to Dh and said even more crossly, and again, loud and clear as a bell, 'YOU'RE A VERY - NASTY - MAN!'
I swear, one of the carers who was busy nearby, nearly wet herself laughing.
And we were in fits later. Chocolate was evidently a Very Serious Matter!
Poor old thing, though - her former self would have been so mortified to see what she'd become.
By then, though, she'd had dementia for so,long that sadly had become 'normal'.
