The coach first explains the four parts of NVC with simple examples: observation, feeling, need and request. Then you take a real conversation from your life and rebuild it using these four parts.
A large part of the work is empathic listening: guessing the feeling and need behind the other person's harsh words. Role play in sessions helps the sentences sound natural and in your own voice, not like a textbook.
NVC can feel harder in Persian because politeness rituals (taarof) and indirect speech are part of the culture. A coach familiar with that culture helps you apply the method in a way that respects it.
