Avoid interaction as much as possible, but don’t make a big deal out of it because it will give them ammunition against you.
When you do have to talk to them, talk about boring things, like the weather. If they ask questions, give vague, uninspiring answers that don’t invite more questions.
This will quickly bore a narcissist and shut them down.
10. Walk Away
The best way to truly shut down a narcissist is to walk away from them. If all else fails, you just have to physically refuse to stay in the conversation.
Even if they keep talking, simply turn around and walk away. If they follow you, close the door. Put headphones on. Pick up your phone and call someone. This will force them to eventually just stop.
11. Remember That You Cannot Control Their Reality
If you recognize that you can only control yourself and your perception of things, you will be less likely to try to fight back against a narcissist.
You can’t challenge someone else’s perception of you. They will think whatever they want to think about you no matter how much you fight against it.
