You know, whenever I see somebody say they think Ron and Hermione's fights are vindictive and a main reason why they shouldn't get together there's always this little voice that pops up in the back of my head saying "Gilbert Blythe! Gilbert Blythe!
Strange, but completely true.
(And no offense to anyone who doesn't like R/Hr, I just always find myself countering that particular reasoning by fondly remembering Anne of Green Gables. :D)
