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?
Or, make it all about you, but only with that person.
“When that happened to ME…”
“That reminds me of the time <totally unrelated thing in your life>….”
“I have a friend who’s an expert in that and HE said….”
[edit] actually, what I do with those people is ask probing questions, things they couldn’t possibly know the answer to. As a last resort, I insert something that I know someone else in the group is interested in, and invite them into the conversation, exiting at the same time or shortly after.
Also, holding a plate or glass and then realizing you have to go refill it and making yourself scarce works.
