If you try to read "A Confederacy of Dunces" you WILL be able to throw a book away.
Tossing "The Stand" away was just a matter of being unwilling to foster the book off on friends, none of whom were into King.
"The Stand" was simply outside of my normal interest. I do that frequently. Sometimes I win, sometimes I loose.
But I am fully confident you and 99.9% of the people here would gladly toss "A Confederacy of Dunces" no matter how interesting it looks.
