"A person with an oppositional conversational style is a person who, in conversation, disagrees with and corrects whatever you say. He or she may do this in a friendly way, or a belligerent way, but this person frames remarks in opposition to whatever you venture. I noticed this for the first time in a conversation with a guy a few months ago. We were talking about social media, and before long, I realized that whatever I’d say, he’d disagree with me. If I said, “X is important,” he’d say, “No, actually, Y is important.” For two hours. And I could tell that if I’d said, “Y is important,” he would’ve argued for X." Thanks to http://psychcentral.com I have to deal with someone who ALWAYS has to disagree with everyone about everything! Do you?
