You know, the guy who’s been having that same angry conversation about the same fucking thing he’s been obsessed with for the last 5 years and demands that you take his view while going on long monologues and then immediately interrupting anyone who tries to get a word in edgewise? And then goes into a weeks-long suicidal despair if you try to leave the conversation? Any way to deal with that?
Bring an airhorn and blast it every time they say something undesirable.
Or visably put in noise canceling headphones when they start talking.
