It's entirely possible to have rewarding & meaningful interactions with narcissistic people. Here's my process.
First, realize you're not so much better. Don't expect too much.
Next, don't insult them. Be aware of power games; don't get confused. Be straightforward.
Generally avoid putting yourself in a situation where you need something from them. If they offer a favor, accept it (if you want) and say "thank you".
Finally, don't try to fix them. Be simple. Offer them your time, and not much else.
You'd be surprised at how many narcissists are relieved and happy to meet someone who behaves in this way.
