I love how age doesn't slow them down in the Wizarding world. I don't know many real great-grandparents.

I am a packrat, but I'm not nearly as organized as Ginny -- and I totally sympathized with Harry's pangs of regret that the baby books for his younger children weren't filled in (we didn't even buy them -- did I mention I wasn't very organized?).

I agree with others who said this rang true and made Harry and Ginny seem very real.
