There is silence, for example, on the other end of the line, somewhere in between phrases like: “Is this the right number?”, “Can I take up some of your time?”, “I don’t really know why I’m calling…”.
Silence can also choke you, for example during therapy, when you have to think back to events that took place a year ago, too terrifying to put into words. Even if the words can be found, silence ensures that they do not find their way out.
