Supposing:
5/ R: (deep breath) I see that you are deeply emotionally invested in the tragedies that bad building can cause.

6/ A: Yes I am
7/ R: I would like to also celebrate the achievements of people who have invested in improving the regulations here. I need to take time to celebrate the positive sometimes.

I agree that some people only have one style which is monologue + applause. I am culpable of this when particularly emotionally aroused by something.
But if I had been Anne in this situation, perhaps I wouldn't have known that this was a deal breaker for you unless you were explicit about that by word, tone of voice, gesture, etc.
Writing both sides of the dialogue is something that you've done here before - perhaps it's a gestalt-y thing that I'm unfamiliar with. Being more of an embodied person I would tend to affirm A which brings her into the present with me, before launching forth. I would also check whether my tone and body communicate my intent correctly: is this playful/ confrontational/ flirtatious/ just making social noises.

What was your emotional intent/ need? Was it something intellectual, or something more deeply connected to your identity?

Again, as an embodied person I would need to get my intention thoroughly behind me before stopping someone mid-flow in some emotionally obsessive rant. "Stop!"... but then I need all of my intent to turn the flow. Don't depend on the other person... especially if she's caught up with her own movie of hosting a book launch.

I have a next door neighbour who lives totally inside her own world view and I wouldn't even try to intervene. I have another neighbour who is a bigot but we have learned to laugh about our disagreements: he thinks that I'm a bigot too, but there is a connection because it's meaningful to us both to create one.

I looked up Emerson but didn't get illuminated as to what tonic speech means... It's possible (???) that A's speech is fuelled by emotion; R's speech is fuelled by ideas; S's speech is more about tone and gesture - so there is a criss-crossing of wavelengths?

Please explain indicating which wavelength I should tune into SMILE - do you remember the days of pirate radio stations?

I am going to send you something... I gotta read it myself again first.
