It's funny to be discovered by a lot of people who didn't know you before. People always used to say 'Do you shop at Home Depot?' or 'Does your kid go to such and such school?' They want to know why they know me even if they don't know my name. I don't think that's a bad thing by the way I think it's nice to be kind of anonymously famous.
The great secret that all old people share is that you really haven't changed in seventy or eighty years. Your body changes but you don't change at all. And that of course causes great confusion.
