Thanks?

Sometimes my students leave me little notes--mostly nice ones. :) I have a drawer in my office that I keep them in and look through them on days that I need a little pick-me-up.

However, the one I got today wouldn't fit in the drawer, so I took a picture of it for you. (It was written on my overhead projector, so this is a picture of it projected onto the screen to make it easier to read. Sorry it's still a little fuzzy.)


I'm not really sure what to say. There are so many ways to take this.
1. "Thorn" (I'm assuming that refers to me...darn that pesky little "e") is equivalent to "rock is." ...That's a good thing right?
2. (If you ignore the apostrophe) Thorn is equivalent to collections of hardened minerals.
3. Thorn is a possession of Rock's. Not sure who Rock is...maybe it's a prediction?

Thanks kids. I'm sure you meant well. :)
