If verbal diarrhea is a thing that so/sx, sx/so or just so-first/second people relate to as a hole, then that is cool to know. In real life, among a friend I think is definitely so (problably so-dominant), I can see how being able to contribute verbally can make the person feel comfortable or uncomfortable in some situations. Of course, every enneagram type will still experience it differently (and the friend identifies being a 4w5) so I still need to pay attention to the nuances.
