Travel Across Africa
For six hours we shot through the barren（荒芜的）landscape of the Karoo desert in South Africa. Just
rocks and sand and baking sun.Knowing our journey was ending,Daniel and I just wanted to remember all
we had seen and done.He used a camera. I used words.I had already finished three notebooks and was into
the fourth,a beautiful leather notebook I'd bought in a market in Mozambique.
Southern Africa was full of stories and visions.We were almost drunk in sensations.The roaring（咆哮）
of the water at Victoria Falls,the impossible silence of the Okavango Delta in Botswana.
And then the other things:dogs in the streets,whole families in Soweto living in one room,a kilometre
from clean water.
As we drove towards the setting sun,a quietness fell over us.The road was empty一we hadn't seen
another car for hours.And as I drove,something caught my eye,something moving close enough to touch
them,to smell their hot breath.I didn't know how long they had been there next to us.
I shouted to Daniel:"Look!"But he was in a deep sleep,his camera lying useless by his feet. They
raced the car for a few seconds,then disappeared far behind us,a memory of heroic forms in the red
landscape.
When Daniel woke up an hour later I told him what had happened.
"Wild horses?"he said."Why didn't you wake me up,Sophia?"
"I tried.But they were gone after a few seconds.”
"Are you sure you didn't dream it?"
"You were the one who was sleeping!"
"Typical,"he said."The best photos are the ones we never take."
We checked into a dusty hotel'and slept the sleep of the dead.
Sophia wrote about her experiences in notebooks.
