stream of conscience-y

I think that's why I relate to the OP tweet so much. When I'm writing a text or comment, it's usually in a inner-voice type of thing where I'm imagining myself speaking directly to the person. And I definitely speak with lots of parenthetical "bonus thoughts"

When I'm writing out something important, an official letter or work email, etc. I take my time to form the full thoughts and put that all down in writing as properly as I'm able to.
