"If it is a rare first edition, then it carries much more weight if nobody has ever opened it, much less read it."
Now we're getting somewhere. Like "all" and "brother" could "rare" have many meanings one of which being that even though the book was published recently you bought one of only the few that were sold before they figured out it was a dog or the author was caught in a compromising situation or so far out no one would read it except someone who had no feet in reality?
Hmmm...good question. Do I get to define "rare"? Can I use it on eBAY?
