One Christmas, my SO gave me the book _A Confederacy of Dunces_. I hated it, and only finished reading it because it was a gift (and I wanted to at least give it a fair chance). I talked to a friend of mine (a former English teacher at the University of Alabama) about the book, and it turned out it was one of his favorite books. We ended up having a great discussion about it.

I think it's important to keep in mind that others aren't you, they have their likes and dislikes and it might be a good thing to learn why they have the opinions they have.
