Why was Gandhi arrested?, asked my 7-year old son this morning, not looking up from his encyclopaedia as the bowl of Weetabix in front of him grew gradually soggy. My answer was a long-winding and entirely inaccurate ramble through colonial history. And in a final flourish to the story, I added that Gandhi was a huge advocate of non-violence and that he managed to  bring the formidable British empire down without ever striking a single blow. Well, said my son, Toby’s parents will definitely not like Gandhi. Why, I asked. They tell Toby to hit anyone who hits him, he replied. His Weetabix was now a stodge.
