I know what you mean ... however, I think we're so used to the action/adventure of Harry & Company that a regular, everyday like life might be considered "too boring" in comparison.
Don't get me wrong ... I'd love to read anything more about Harry & Company!!!! I would've especially loved reading about the various engagements and weddings! Would've loved to have known how Harry proposed to Ginny, Ron to Hermione (after all, he isn't the most eloquent), etc. I mean, can you imagine how crazy Hermione must've made Ron while planning their wedding?!?! lol! I know that JKR told us what the rest of them did w/their lives (ie: Neville teaching, etc.) but it would've been nice to have it in the book! I also know that JKR said that she wrote down every couple and their children ... would've loved to have known who Malfoy married (I like to think Pansy), etc.
