Here's a little piece of authentic writing from my house this summer. I just got through scolding my boy for messing with his sister and I noticed that he was over in the corner concentrating on something. As I got a little closer, I noticed that he was writing a note for a very real audience - me - with a cryptic message.
As it turns out everyone except me had been ill the last couple days and Phillip thought now was as good a time as any for me to take my turn. More evidence that with the right motivation students will write without even being "prompted". We celebrated our little tyrant's note and searched his backpack for arsenic.
