A little kid at my school assembly grinned up at me after the show. ‘You remind me of somebody I know!’ he chirped. ‘Who?’ asked I. ‘My Gramma!’

It wasn’t the first time my internal chronometer got a jolt of sudden aging. My dad’s friend told me one day I looked more and more like Frieda, my paternal grandmother he’d known as a child.

All this grandma talk can get a girl cranky in the bones.
