ohhhhh Lily!!!
I hope her innate math talents manifested eventually, despite the evil teachers.
Evil is not always deliberate. Ignorance can foster some of the greatest evil. Even good intentions or convictions of one's "rightness" and moral correctness is no deterrent to evil!

I love your believe that somewhere in me, a brilliant mathematician dwells, locked up in a dungeon perhaps, one day to be liberated.

Hmmm, maybe snook's grumpy fairy prompt or your bullfrog prompt could lead me down this path....
