I don't really know too much about DD. From what I've seen, though, he's a very enthusiastic young fella who tries hard for all sorts of things, sometimes a little too hard if you can say such a thing. Can be sensitive and fights back, I think with Gobo a lot? I think it's those two... anyways, he's alright in my books as he's improved over time (at least, I think he has) which can only lead to better things. It's always nice to see enthusiastic people at EoFF as they generate a lot of activity.
Bettering? Just not take things too personally and if someone annoys you, ignore them and it'll pay off in the long run. You're better off thinking about yourself and those you like than people you dislike. Of course, this is all based on assumptions so maybe I'm just missing something completely. =x
