The images on the television screen are now so familiar we become immune. Unimaginable numbers of people suffering and dying in a part of the world we know little about for reasons we know even less. What is it that we feel? Sadness, pity, a sense of anger, a sense of hopelessness? So we make the right noises, perhaps make a donation to the relevant charity and move on to the next news item. Yet the people suffering are just like us; the only difference is that we are lucky enough to have been born here.
