When I went home a few years ago, I saw an old lady who's been around the village for years and known us since we were all born. She stopped and said "your grandmother will never be dead while you're alive." just like that - no hello or anything!! I know it sounds a bit odd, but I thought it was very moving. I always remember Nanny telling me that when she was young she was known as the girl who was always smiling, so if that's how I've turned out too, I'm definitely OK with it!
Also, I find myself saying EXACTLY the same things to my boys that mum said to all of us as children, but not consciously. These words just pop out of my mouth as if from nowhere, and I think 'good god, who said that?' lol!
