I was watching the Johnny Cash biopic Walk the Line again the other day and it threw up a question for me. The film starts by recalling Cash's childhood in rural Arkansas. His older brother Jack, who met an awful end thanks to a wood saw accident, was held in high esteem by his whole family. Jack Cash's ambition was to be a Preacher, he wanted to help people. At that time, of course, this was seen as an incredibly noble and honorable thing to do. If you wanted to help people in your community spiritually and emotionally this was THE way to do it. Given the demise of Christianity in this country what does the teenager who wants to help people aim for? If he chooses the cloth, he does so in the knowledge that fewer than half of his community will take his advice seriously and even fewer would come to him for it. Teacher? Doctor? Volunteer? Psychopherapist? Politician? Green Party politician? Mummy when I grow up I want to be Caroline Lucas.
