from what I have come to understand, throughout my life, is that a sigh is a signal from an individual that they want attention. I've realized that people sigh when they want someone to talk to or vent their frustration. I've even noticed that I will do it from time to time. next time he it does ask him what he is thinking about. he has to be thinking about something while he is doing it.
