I have an ENTJ mom. My mom and I used to argue a lot which drove my sister crazy but it was more about my inability to get homework done and get ready for school on time than objective disagreements.
People say that it is impossible to argue with me. People who don't know me well think they've convinced me in the beginning and change subjects, but in my head, I am disagreeing. Arguments with people who know me well enough to realize I disagree end when they realize they can't convince me. I am fine with other people seeing it their way and me seeing it my way. I can see how this might annoy someone. If Ms. INFP is like me, then I feel bad for Ms. ENTJ.
