5. We had a son, [Kumalo] said harshly. Zulus have many children, but we had only one son. He went to Johannesburg, and as you said—when people go to Johannesburg, they do not come back. They do not even write any more. They do not go to St. Chad's to learn that knowledge without which no black man can live. They go to Johannesburg, and there they are lost, and no one hears of them at all. (Pg. 39) AND [Kumalo] is silent, his head aches, he is afraid. There is this railway station to come, this great place with all its tunnels under the ground. The train stops, under a great roof, and there are thousands of people. Steps go down into the earth, and here is the tunnel under the ground. Black people, white people, some going, some coming, so many that the tunnel is full. He goes carefully that he may not bump anybody, holding tightly on to his bag. He comes out into a great hall, and the stream goes up the steps, and here he is out in the street. (Pg. 47)

Based on these two passages, other than being afraid, how does Kumalo feel about the city?
