It may be cause I was raised by an unhealthy ENFJ, but I am extremely all three of those things. I do keep negative reactions to myself if it is someone I like and don't want to hurt and nothing productive will come out of it. When I speak in class, I am always very blunt, sometimes even undiplomatic but I don't mean it that way, but I won't wrap a pink ribbon around a question or opinion when it is a discussion. I always rate movies that I see and analyze the aspects that were done well and not. If I know how to judge, I will and I take great pleasure in it. When it comes to movies and books, my standards are always higher than my ISFJ friend, but when it comes to food and customer service, she cares more and I am just like ... uhm ... matters not ... Saying nice things to someone actually makes me feel a little ill ... If I am being sweet, I am also being a good percentage sarcastic.
