This was more like two leassons actually, regarding Dumbledore, you're right, the lesson is that because we made a mistake doesn't mean were are a bad person. But that wasn't the original "intent" let's call it for Dumbledore to bring up that subject. Depending on Dumbledore the story would have stopped before Harry asked why his father did it, and that was me working through Harry so that Harry would kind of learn that lesson so later on, in "Life Goes On", (you know where sinceyou've read this before, not telling the new readers!) Harry recals this lesson.

So I needed to bring this up, but as I said Dumbledore brought this up to show Harry that people's opinion can change a lot, and that is what I meant by thinking this would fit when everyone was hating and afraid of Harry because of him being a parselmouth. 

But, you are right, the lesson I wanted people and Harry to remember was that  just because we made a mistake doesn't mean were are a bad person,so he can remember that one you know when, and I'm glad that's the lesson that stands out, and not the one about Dumbledore being unpopular once.  (He,he. Did my job!)

Thanks for all the input. I always enjoy discussing with you!
