Theatre as we know it today has continued to transform over the centuries, retaining its essence - that cleansing that each of us expects when we enter the theatre: catharsis. The need to make theatre comes from two branches with a common root: artistic expression and reception. Theatre about social problems that can be meditated on and debated in the community creates the space from which a solution can emerge. The difference between this form of theatre and classical theatre based on drama is the way it is created. The participants who experienced the events are the main authors, they know what happened, how they felt, what they thought. Social theatre does not bring to the stage what the author thinks about what is happening in a situation of marginalisation, poverty and abuse that he or she has not experienced, but brings to the stage the reality outside the world of the artist. Performances created by directors and actors together with non-actors start from the less bright experiences of society: young people from troubled families, children abandoned in the protection system, victims who want to change their condition, adults who have power and abuse it, etc. The social expert, through his dialectic, uses the methodology of social theatre to help young people identify the problems they face every day and find solutions to solve them together. Based on ethical values and principles, the social expert, through his professional integrity, promotes respect for people, positively valuing the contribution of the beneficiaries in the joint work to solve the problem that has arisen in the community.
