Hopeful, that's a good word for it.

I keep thinking, you know, about the two of us when we were back in Hogwarts. About how they all made sure you and the other halfbloods in fostering didn't 'bother' us purebloods and all. I wonder sometimes whether in another world we would've been friends, or if House rivalries would have still kept us from ever getting to know each other.

I don't know if I've ever really said, actually, but I'm still so sorry I never told those wankers who never stopped giving you a hard time to shove off.
