You use to took your notes in substitution cypher?!

I did. Not all the time, though. Based on the notebook I found, my preferred method of note-taking was mirror handwriting.

but it would be better if you could use it for yourself right?

::sighs:: It really would be.

Have you ever thought about being a book publisher instead of a teacher?

I teach writing, so being able to unknot writing is a vital skill in what I do. I have thought about becoming a book editor, but I love teaching too much to give it any serious consideration.
