User blog:GrouchMan/D.W. - Trustworthy or not?

Everybody knows D.W. Read throughout the years, has behaved like nothing but an extremely selfish, spoiled tattletale little brat, but does anyone think she is capable of truly changing into a trustworthy young lady in the future? I'm not totally sure; she's done an AWFUL LOT of unacceptable things to poor Arthur over the years. What do you guys think?
