It's irritating at the very least, someone assumes what you're thinking or feeling, or what you need to do. Perhaps you have someone in your life right now who is just certain they know what is true for you. In an extreme way, perhaps it's even an abusive relationship. Do we ignore their projections? Do we not take them personally? Do we stay or do we go? If we find that projections in general aren't ultimately based in reality then how do we find solid ground when it comes to relationships?
