One for Sorrow

I noticed that too--but it's not surprising. H/G in the books is always about being told how they're great together, but Ginny mostly just is there to say whatever Harry needs/wants to hear at that moment. People hung onto her "Lucky you" comment in OotP as a sign that she'd disagree with him, but that's just there because the author thinks Harry needs that at the time. It's not really a sign that she thinks he's arrogant or doesn't think about her. It's like just proof that she's supposedly spunky, but most of the time she's just going after people he's annoyed at. Unfortunately this doesn't leave much for them to converse about besides how awesome it is that they're a couple. Ron and Hermione at least have their constant bickering about whatever Ron did lately.
