JLPT N3 Reading

A bundle of letters from twenty years ago turned up in a cupboard at my parents' house — from friends in my student days. Rereading them, what surprised me was not the content but the handwriting. On days written in a hurry the letters are messy; on calm days they're neat. The writer's state that day is preserved on the paper. Email carries feeling too. But as long as it's shown in the same font, it can't convey health or mood. Whether that's a good thing, I don't know. Q: What does the writer say about the old letters? — The handwriting shows how the writer was that day.
