This aspect will make your communication frustrating at best. Your friend will have a hard time listening to you as the person you truly are inside. When you go to them for advice or just a friendly, supportive sounding board, you'll find that they often won't hear what you're actually telling them about yourself; instead, they'll hear some filtered version -- filtered through their own perceptions and their own, personal way of thinking.
But how they think about and perceive the world has little to do with where you're going in life, and that's where the problems will begin. Their advice for you won't hold much relevance for the lessons you're trying to learn or the kind of person you're trying to become. Well-meant as their ideas may be, you'll find you're better off charting your own path and following your own instincts.
