While out cycling today I decided to stop for tea 'n' coffee cake at Burnham Beeches nature reserve cafe. As I arrived and put my bike against the fence, there was a couple sitting down at a table. The lady of the couple looked at me and smiled a lot. I wondered if they were anyone I knew so I went over to speak to them.I said, "Hello?" She beamed, "Oh, hellllooo. I was just thinking how lovely you are." The husband explained, "She's got dementia".
