"Jean and I got married in 1961 on April's Fools Day. In 1985 Jean was diagnosed with MS and 15 years later with Alzheimer’s. 2003 was a major turning point for us because she fell down the stairs and broke her ankle, resulting in 96 nights in hospital.
"I wasn’t happy with the way she was being treated. It wasn’t the nurses’ fault: there weren’t enough of them and I don’t think they'd ever been trained in dealing with someone with dementia. No one talked to her.
"Each day I came home and made a card. Jean loved gardening, so I used to photograph flowers, print the card and write some words to her. In the morning when I came in, I’d put it on the window ledge. And the next day I’d put the next one there, and then the next one.
"As the cards built up, the nurses would come by and say, 'Hello Jean, what card have you got today?' Not only the nurses, but the cleaners, anyone who came to the ward, the doctors, even consultants got to hear about it. So Jean, who’d been more or less ignored, suddenly became a real person. And it made all the difference in the world."
