My grandparents were kind people. And they were also unthinkingly vicious racists. They talked of "niggers". "Blacks have only come down out of the trees in the last few years" my grandfather explained to me. "You can't expect them to be civilised". "Get that out of your mouth" my grandmother shouted when she saw me sucking on a penny. "Some filthy Chinaman’s been touching that!” They called anyone they suspected of greed a Jew.
The dog ran ahead with busy nose to the ground. As I walked, I listened on my iPod to Roald Hoffmann, an elderly Jewish man, recount his experiences as a child in Nazi-occupied Poland.
