What I highly dislike is insistant incorrect experts. I've challenged many of my friends to suggestions that they have made about certain parts of the books and even though they're wrong, and you know it, they will argue with you until the end of time. And it is so frustrating. Also when it comes to quoting a certain line in one of the movies and they keep getting it wrong and you try to correct them and they say they're right. BLAH!!!
