Book excerpt: Some of my best friends are white is a collection of sharp, satirical essays on contemporary South African issues from the point of view of a successful corporate professional - who just happens to be Zulu. Crossing various controversial, amusing and downright confusing racial divides, the title delivers a healthy dose of black - and white - humour as it explores some of the rainbow nation's defining characteristics, its many colourful characters and its myriad mysterious idiosyncrasies.
