How do you work with a narcissist at work and family events?

Google "grey/gray rock technique."  The idea is never to give them enough information about you  to use without enraging them by actively ignoring them.  The theory is that they will get bored with trying to get their narcissistic supply from you and will hunt for other victims.  Howbeit, you can skip a lot of unwanted drama be making sure that they have as little real info about you as possible.

NGDCs.. IDK .. I am not sure  .. maybe they are to be left to their enjoyments .. doing what is right at the point of interaction ..
