A Learning Experience

How would things have been if Harry had got to know Snape and his Snakes better? A 'Harry in Slytherin' story. Don't groan; it's not that bad! Warnings: mention of sex later on (very mild); typical teenage swearing (mild) and corporal punishment (not graphic or extreme). Please enjoy and share your thoughts with me. (Note: the beginning is heavily inspired by Asterix Tutnix.)
