I was re-reading the wonderful "Diary of a Provincial Lady" recently. My favourite character, apart from the main one, is old Mrs Blenkinsop who is master of what is known today as humblebragging:
"People say, she adds deprecating, that just her Smile does them good. She does not know, she says, what they mean. (Neither do I.)"
However, I was disconcerted to realise that old Mrs Blenkinsop - invariably referred to as "old" - was 66, ie a year younger than me. That was written in 1930. It could just be comic effect, I suppose, but it is never suggested that she isn't genuinely old. I wonder if old age was reckoned to begin earlier then. My mother said that her grandmother always dressed in black from head to toe and seemed ancient, even when she could only have been in her 60s.
