well, memories abound, Philip, but I don't know how relevant they are! I remember disliking Sister Ena, so the episode with the dish-smashing that Richard speaks of didn't surprise me too much! But it was a bit surprising, that a Sister could get so out of control. Sister Cora could get mad, of course--we were a trying lot, I don't doubt! But she would just become very red in the face, and her glasses would flash, and she would threaten us with stopped pocket money, early bedtime, whatever. But she was never to my knowledge abusive in any way, or destructive.
I had a very unpleasant encounter with Sister Ena one time, when I went and sat on a swing that one of her girls thought was hers. Sister Ena came storming out, and very swiftly slapped me hard around the face. Such things aren't very endearing. And I learned to steer clear of her after that. OOOh, am I telling tales on the Sisters?! But I probably deserved some reprobation, no doubt. Would a discussion about fairness and sharing at the time have helped? I think so!
