17-year-old Helena Muffly wrote exactly 100 years ago today:
Wednesday, September 25, 1912: Was rather surprised at the mark I made yesterday. Didn’t think I would hardly get that. Twas the kind that dummies get.
Her middle-aged granddaughter’s comments 100 years later:
Whew, I’m surprised that Grandma did poorly on this geometry test. She never worried about the upcoming test during the days preceding the test, and the previous day she’d merely written, “I had a test in geometry.” and then moved on to other topics.
Usually Grandma had a pretty good sense of how she was doing in classes, and if she needed to study—though sometimes she never actually got around to studying.
