I thought about posting this without sound, but…meh. It’s a good illustration of why one aspect of an interaction, sound in this case, isn’t reliable in and of itself. All aspects, such as body language, turn-taking, etc, have to be taken as a whole to gauge whether an interaction is healthy or not. That said, these two know each other and I know them both, so I already have an idea of how they are together. This wouldn’t be my first step if they weren’t familiar.
