I knew that grandmother when she was in her eighties and nineties, mostly. She was a down to earth, practical person and very old, arthritic, wrinkled but she would look at herself sometimes and say all she really needed was a facelift.
Later I saw a picture of her taken in her earlier seventies, before I was born. She was still old but comparatively younger, and wore a beaded crimson blouse. She had the offhand, casually beatific look of a woman who knows she is beautiful without effort.
People talked about her marvelous personal characteristics and did not say she had been a beauty but I suspect she was. It would be why she was surprised to see herself now, and said all she really needed was a facelift.
