Let’s take things as they come
Rather than tensing up to be ready to pounce, in reaction to what happens, let us try to accept events for what they are. Has your neighbor just flooded your living room? Good. Do not rush home in the heat of anger. Consider what’s going on. What action should you take first? Put a basin under the leak? Very good. Then warn your neighbor about the damage you notice at home? Perfect. You can go ring the bell. Therefore, by adopting a positive and practical state of mind (since you have to be in this situation), you will remain calm and will manage to resolve the problem at hand without creating unnecessary tension.
