Yes, which would be why I namechanged.
To save you the bother, it was Streatham Hill and Clapham High School. In those days it was on Wavertree Road in Streatham, which is now just the junior school I believe. Had a hideous snot-green uniform back then. The former journalist Cordelia Kretchmar was in the same class.
HW's mother was an opera singer. Sang at the centenary service for the school at Westminster Abbey in I think it was 1987, though not sure on the year.
She was very pretty, good academically, one of the top dogs. I can still remember her rage once when she and a pair of her little pals grabbed my bag and started throwing it to one another so I couldn't get it, and I just started to laugh over how fucking stupid it was - and they were. Her face contorted with disgust and she hissed, "Why are you laughing?! This isn't funny for you!" I can visualise her that moment, all these years later. Silver blonde hair, slim, tall. Suddenly much less pretty - as if her personality was suddenly written all over her face.
That's actually one of the nicest stories I have of her. At least one of the rest, as I have no evidence all these years on, would be actionable. But yes, I remember her, and in my (clearly subjective) view, she was deeply unpleasant. To the point I shudder every time she's on my screen, or her name appears in print, all these decades on.
