As a school child at the time who absolutely hated it I would say it's the only good thing she ever did.
It either sat in the window all morning in summer, or sat over a caste iron radiator all morning in winter. Then when you got caught tipping it down a drain or pouring into Sally Devlin's duffel coat pocket you got a twat round the head and a lecture about starving children in Africa. Still, Britain was a kinder, gentler place back then.
Probably not quite old enough mate. So ER can't, upon reflection, have been the kid who found a dead crow in the playground and hid it in the teachers desk. Pity; I always wondered what happened to him.
ER used to run around his cave playing with toys carved out of woolly mammoth bones, I doubt crows had even evolved back in his day. It's very likely that he was one of the creepy old men that came to watch the kids play footy in the courtyard though...
