[squarebear]

Yes.

[McMouse]

No

[rowanwitch]

Absolutely.... but it's better than keeping going to no avail....

hardly anyone ever changes their view on the spot, they may take on board new information and modify their view next time a subject comes up but they'll never do it in way that they'll lose face. This is merely acknowledging that the discussion is pointless to continue given the intransigence of the protagonists.
