appears i'm all alone in my opinion of harry in OotP oh well, but tanuki said:
It's not so much attention seeking, because attention is kind of the last thing Harry wants. Partially, he wants everyoe to believe him. People have an unpleasant habit of assuming he wants to be famous, when all he wants is a normal life with his friends and a decent family. Couple that with a frustration stemming from a feeling of having no control of his life (and with so many secrets being kept around him and people continually trying to protect him by excluding him, these feelings are not unfounded) and you get one very upset teenager
and i would agree with you there tanuki, i can understand why he got so angsty and he hates attention and the whole fame thing. i think the thing that annoys him most is people constantly keeping secrets from him to 'protect' him when he's proved time and time again that he is more than capable to cope with things. until people start to 'protect' him from the truth, and i think that only knowing half the truth is much more dangerous than knowing the whole truth.
