I understand that the DM attack was based on what Ralph Milliband wrote in his diary when he was 17 and just arrived in England after a traumatic escape from Nazi persecution. Only 17, traumatised by his recent experiences and in an alien country with a different culture, what young person would not write in their diary feelings that dissipated as time progressed?
I spent my childhood travelling the world with my parents and yet, when in my early 40s I went to California for a holiday I was amazed to find myself suffering from culture shock for the first two days. I hated the country, the people, the culture. After two days, recovery from jetlag and with a couple of night sleep I loved my holiday, the country and the people. Fortunately I do not keep a diary or have a son in the public eye.
