I was once a student and now I'm a teacher so I LOVE Harry and Snape stories because I can see both sides. I didn't start reading Harry Potter until I was in college but I'm a huge fan nonetheless. When I started writing fanfiction, it was to answer the unanswered questions from the books. It's more of a challenge now that the final book has been written and many of the questions answered. My latest story (Losing Harry) was an attempt to see if I could make Harry Snape's son...but not...and still follow canon.
