You know all those times you see video footage from developing countries that show people living in ramshackle huts or seriously run down buildings, surrounded by rubbish and ill-looking animals? Well, there’s something about a screen and thousands of miles between you and what’s on that screen that desensitises you to it, I’ve found. Seeing it in person though at Nanyuki, a market town in central Kenya, caused a simmer of disquiet when viewing through a car window screen that bubbled into guilt once I got out and walked around.
