There's this great little story today about a man who saved a small group of report cards from the Manhattan Trade School for Girls and the stories he discovered there. This is such a great moment of an amateur historian working with a primary source. I love that he contacted the families and gave them information they might not otherwise have.
That said, I'm not sure if I want my future family members seeing my report cards. Mostly they are decent, but if there are the kinds of notes that these have, then really, even I don't want to know.
