I think it was a Goerge Carlin bit — “Vuja de… the feeling that none of this has ever happened before…” But yes, for some of us old farts, that suddenly scary feeling that this aisle/street/neighborhood is completely unfamiliar, and we should know how to navigate but we can’t recall, when our life up to this point was just going along on our gut… that can be terrifying. Even the fourth or tenth time.
