I think Dumbledore was a tad of a loner. Relying only on himself, so he didn't trust others with what he thought was important information, you know that phrase "If you want it done right do it yourself." ? I think he was a little too fond of that phrease and thought that if he gave away information and delegated duties things wouldn't come out just as he wanted.

That's where i thought my story might be different, my Dumbledore still spent the majority of his life being a loner and because of that still holds to some bad habits, but at the same time he is not alone anymore and his new "family" manages to break through those habits. So he has help.

Thanks!
