On this very forum actually. Gorse, may he rest in peace, once thought I had some kind of grudge against him and called me out on it. It was totally 100% my fault though, because I didn't stop to think that me just inserting myself into an existing conversation out of nowhere totally looked like I was trying to swooce in and one-up him in some way, while in my head I just thought I joined a conversation. Really blunt behavior on my part. I felt really fucking bad and apologized profusely, and we made up, but I still cringe super hard if I think back on it.
I'm really glad he forgave me, because I really didn't mean anything, and was kind of shocked that I hadn't picked up on the vibes, because I'm usually good at reading the room. One of the worst feelings in the world to me is accidentally offending people.
As for the "oddly specific" part, he thought I was being literal when I used the word "conspiracy", but I hadn't registered in my mind that he already thought I was accusing him of something.
