I'm currently reading Harry Potter und der Stein der Weisen.
I am managing to comprehend a bit of it (I'm far from fluent in German) although the first sentence in the book is really confusing to me.
What I can't seem to understand is the following sentence:
Mr. und Mrs. Dursley im Ligusterweg Nummer 4 waren stolz darauf, ganz und gar normal zu sein, sehr stolz sogar.
I would interpret that as:
Mr and Mrs Dursley in the number 4 Privet Drive were proud (on it?) absolutely proud to be normal (very proud even?).
This just doesn't make sense in my opinion but maybe I'm over analyzing it? I just can't see what the need is for the words darauf and sogar in this sentence. I'd appreciate any clarification greatly.
