Pedantry is not an indicator of intelligence
Don’t ever correct other people when they are talking, particularly when you are not even a primary participant in the conversation. Unless you are being directly addressed, other people’s conversations are not your concern.
You’re not the Reality Police. And they’re not talking to you. So stay out of it, and for the love of all that is Good, Beautiful, and True, do not ever begin a sentence with the word “actually”. In case you haven’t figured it out yet, pedantry is not a sign of intelligence.
There's one individual that loves to do this to me even though I'm his superior. He tries to create problems out of small details and make it the focus of the team in an attempt to derail the meeting in a direction that will make him look intelligent. When I act annoyed by this he has spread rumors that it's because I'm jealous of what a smart boy he is. The icing on the cake is when I dare correct him privately for any reason because it's my job to do so, he throws a temper tantrum and will write many paragraphs explaining how it really isn't his fault and justifying himself when he throws others under the bus to me for the exact same errors. If I had the authority to do so I would have fired him long ago for this behavior alone, but because he has some valuable skills and can perform well (only when he chooses) and my superiors don't have to deal with this directly on a daily basis, they don't take my concerns serious enough to do anything about it. I do not care what knowledge or skillset you have, if you are disruptive to forward movement of the team, cause turmoil among the deltas through treacherous behavior, and make your superiors life more difficult to try and amplify your perceived status, I do not want to work with you in any capacity.
Doof is one of the most on point characterizations of an archetype ever. Hypergamouse always hits in on the head.
