This note, written by a junior, was attached to the precalculus book she was returning:
Dear Mr. Davidson,
Here is my book. I have enjoyed it thoroughly. I read it when I was feeling down, and it raised my spirits.
“I poured my soul into this book, and I hope the lucky student who has it next year will enjoy it as much as I have.”
The inner quotation was carefully attributed to a classmate, complete with a © symbol. (And there was no smiley or other emoticon to spoil the ironic tone.)
