The woman writing it probably had no idea that her daily chores and interests would fascinate another woman so many years later.

I always think that people like this would be most gobsmacked that it wasn't the important stuff that the historian wanted to read about, like the wedding they went to or the political events they witnessed, but instead it was the most mundane, boring stuff about their household chores.

It would be like a historian of the future combing through the preserved printouts of Peg's livejournal for all the stuff she said about her commute -- by car, by train, by bus, by bike.
