It was Nat’s 16th birthday. He had received presents and good wishes from his parents, told that ‘No he wasn’t going to be allowed to buy a motor bike’ and was receiving advice from his medical father about the dangers of drugs.
‘Listen, Son,’ said his Dad, ‘if you can come to me on your 18th birthday, look me in the eye and swear to me that you haven’t taken drugs, I’ll give you £500.’
