I work with someone who seems to have narcissistic tendencies, at the very least. When I noticed it recently, I asked if they would like to consider our other coworkers’ preferences, but they assumed that our coworkers were fine and continued to stay in their bubble instead of checking in. They often try to choose my lunch break time so we could take it together, instead of asking if I have plans for it first. They are constantly posting and reposting selfies on social media and talking about how attractive they are, it seems as a way to build themselves up because they don’t take criticism well.
They once told me that some old friends called them out on it before, but because they couldn’t take the criticism of being called a narcissist, they cut those people out of their life completely, telling me that they were shit. I understand, as I can be insecure sometimes too, and maybe their friends said it in a hurtful way. Maybe they were just shitty friends, outside of that comment. But yeah, I would say this person in particular is quite insecure as well as another narcissist I know from years ago. I can’t say this applies to everyone though.
