Did you ever discover you have or had a nemesis, or distracter?

Over your life have you had or have a nemesis or distracter who seem to have an aircraft carrier sized chip on their shoulder and out of spite if you said it was black they would say it was white, you say sweet, they say sour, you say hot, they say cold, you say fast, they say slow, etc.? They seem to try and use bully tactics or try to rally enough others in with them to get you to quit the job, drop the class, swim from the lagoon, leave the team, etc.? Even when none of the attacks they don’t seem to get it and give it a rest, and you are left scratching your head figuring ”How in the world did I become a burr in their butt?” (To say it politely)
