Code Review Comments - Are They Written?

So what I was wondering as well is code review comments, especially the ones that we are talking about, they are written. And in my experience and also research shows that written communication is quite different from, you know, verbal communication. A lot of things are missing, like social clues are missing, facial expressions are missing, body language, right? So code reviews tend to create more misunderstandings than if we are talking to each other face to face.
