Email is terribly crappy. You completely lose language nuance. I always try to give people the biggest benefit of the doubt even when I'm certain that the person on the other side of the email is a raging asshole.

I think its just "Seeing a face activates friendliness brain circuits." I really do have no other explanation how you can completely defuse situations just by having people sit down and talk at lunch, a bar, etc.

However, my problem is that I have an extremely good command of the English language. This is very useful when I talk as I can make full use of humor, simile, metaphor, florid prose, idioms, etc. to keep things interesting for people.

And I completely lose English as a second language people because they can't keep up with my language gymnastics at speed. If I have non-native listeners and I have to communicate, I have to deliver the talk once to myself, watch it, suppress all of my language weirdness, and deliver it again. It's really tough.

Of course, people who speak English as a second language love listening to me one-on-one as they learn all manner of crazy ways to say things.
