We walked along a high place, and a man was dancing on the railroad tracks.  The train was stuck.  Soon it would be coming towards him.  He jumped off the tracks, considered it, then jumped back on.  He turned to us.

"So this slum is what you call Kibera," he said. "It is the second slum in the world, following Soweto in South Africa.  Do you understand that?  The second biggest.  But soon! Soon! We will overtake South Africa, the place you call Soweto.  Because in Soweto, the guy is trying to rehabilitate, and they are trying to maybe do other things.  So that place will be reformed, ok?  But here in Kenya, there’s nothing being done. The slum is expanding! SOON!"
