my prior knowledge about drama

When little children talk about drama in particular theatre, they would associate it with hero, heroin, villain and happy ending. That was my interpretation once. However, when I become older and entering TESL course, I know that theatre is not just hero, heroin, villain and happy ending. The drama could be tragic or tragicomedy or any other types of drama. Drama could also be intellectual. It would have serious discussion on politic, language, social class and many more. It shows that drama is also good in discussing serious matters in the world.
