WHY IS THAMI STARTING HIS MONOLOGUE WITH A SONG IN ACT 1 SCENE 6?

The monologue simply demonstrates Thami's love of school and learning. Thami is alone onstage. He starts his monologue singing a song in Bantu and then translating it into English; the song is about going to school. He returns again to the story of how much he loved school as a child. His teachers praised him and he was always eager to get into the gates in the morning. When he was in Standard Two, his teacher liked an essay he wrote so much that she asked him to read it about an assembly; the essay was about how he wanted to be a doctor when he grew up, describing how he would treat white people for pay and black people for free.
