So for context I’m a pretty quiet individual. I’m friendly when spoken to, but when I’m busy or just not in the mood to really speak (which is my right) I typically just mind my business. I have this coworker who seems to be obsessed with the fact that I don’t talk much and will often spread things about me that aren’t true because I’m being too quiet. I’m also a pretty witty and firm person. So there’s a couple of incidences leading up to this one. About a month ago, this coworker began playfully roasting a dear friend of mine. I didn’t take offense, as I knew they were joking, so I decided to play into it and joke back. Before I knew it they were getting super butthurt. They got very quiet and left work without saying anything to anyone, then proceeded to give me the silent treatment for several days. When I finally asked them about it, they claimed that I was the one that was in a bad mood and that they were avoiding me because I was “clearly offended” by their joke. Idk if I’m crazy but I’m not sure how that makes any sense. I was chillin, they were the one that was so pressed that they left work and then ignored me for days, but they’re accusing me of being the one in a mood? Several weeks later, I got absolutely slammed at work. One of my biggest pet peeves about this coworker, is that they constantly complain yet do the least amount of work out of everyone. I was running around like a chicken with my head caught off and simply didn’t have time to “entertain” my coworkers. When I was finally able to relax, this coworker began making comments about how I’m very clearly in a mad mood and how our other coworkers should steer clear of me because of it. After I walked away, they continued to lay it on, and proceeded to tell my coworkers that my “Attitude” was bringing down the “vibes.” I just genuinely don’t know what this person is on about. It’s almost laughable. Today it happened again. All of us were standing around having a good time. This coworker began jokingly coming after me, to which I began joking back. They then got very serious, and told me that I was being rude, before storming off and sulking alone for about 30 minutes. After a while, this coworker came up to me and CONTINUED pressing the issue (that was nonexistent until they made it an issue) by asking me if I was still in a “bad mood” and if I was ready to apologize. I kindly told them that I wouldn’t be apologizing, as there was nothing to apologize for. They then doubled down, and tried to get my other coworkers to agree that my refusal to apologize was more evidence of this supposed “attitude” that they claim I have. I kindly told them they were wrong, and the ignored me for the rest of the day. So AITAH? Also how should I deal with this person moving forward. It’s like they are trying to gaslight me and other people into believing that I have some sort of issue with them when I don’t…
