The post is missing that the effect of the described behaviour is very context dependant. For example, I am not afraid of my main client at all. If I get a message from him like "Can we talk" it is just that. He wants to talk about something that is not so important or too complicated to describe it in the message. And if I get repeated phone calls it means that he is either on his mobile travelling and is trying to reach me when he has a signal or that he has a limited time-frame to reach me for whatever reason. In other words: Our communication is not scary by default, and if something scary was imminent, he would surely announce it.
