We saw the chap who deals in gold dust being lowered into a street drain in order to excavate the sludge from the drain, so that he could sell it to another person who had a large organisation where the sludge could be washed and refined to extract the gold from it. He went to look at a room in a house, and he was shown the shared "bathroom" which was filthy beyond my wildest imaginings and it seemed to be shared amongst all the rooms on the staircase.
The man who lived in the beach shack had to tear it down one day to prevent it being destroyed by the council bulldozers, and then his wife had to build it up again when they had gone - she was a little peeved that she had to do most of the work. And she was serving customers the liquor as she was rebuilding the little house around them.
We also saw a gang of young guys who sell books to people in cars when they are stopped at a junction at traffic lights - they are illegal copies of books, and they sell them at knock-down rates. The gang live in the open air in the local cemetery, where we saw women cooking over fireplaces made from bricks, and then they all bedded down for the night on covers on the ground, including a very tightly swaddled baby, which was then just laid on the ground and covered up with another blanket. They live like that, but they have mobile phones - one's mother was calling him from her home in a village outside the city to see if he was OK.
It made me think of the Mennonite saying that we should "live simply that others may simply live" and it reminded me of the child I am helping to sponsor in Niger through the Parent Bloggers network. Perhaps I should live even a little more simply in order to be able to help more. Food for thought.
