I've got a recurring debate with my husband that comes and goes but has been going on since right after the theatrical release of Two Towers as to the merits of Gandalf leaving the Hobbits to their own devices in the Scouring of the Shire. Not 7 hours straight, but an on-and-off one topic discussion spanning a few years!
And I've also kept a reply window open for a whole day while I figured out what to say, but I can't really count that. I also took out the garbage, worked, went to the store, gardened, etc. etc.
Cheers!

P.S. Incidentally,
Elendhel, what
Rings topic(s) comprised the 7 hour conversation?
