I’ve seen a narcissist’s face change in a split second… almost as if they shape-shifted into another person for a few seconds then right back. It happened when I called them out on being a narcissist. Someone told me later that when that happens to a narcissist, it’s called when the mask comes off.
I hope more studies are done to truly show people how office environments bring out the toxicity in almost everyone. I work at a company with less than 50 employees, and while some would get the impression that its size would make my company more like a “family” (hate it when people say that enough as it is), it makes even the least-believable shitty rumor sprout wings and takes flight.
