Most people feel as though because they work or live with someone, they have no way to control the chaos. This couldn’t be further from the truth. Once you’ve identified a toxic person, you’ll begin to find their behavior more predictable and easier to understand. This will equip you to think rationally about when and where you have to put up with them and when and where you don’t. You can establish boundaries, but you’ll have to do so consciously and proactively. If you let things happen naturally, you’re bound to find yourself constantly embroiled in difficult conversations. If you set boundaries and decide when and where you’ll engage a difficult person, you can control much of the chaos. The only trick is to stick to your guns and keep boundaries in place when the person tries to cross them, which they will.
