In life, Andrew was deeply committed to the wellbeing of the young. He co-founded Discovery, an accelerated learning program for teenagers, which went national and is now operating in New Zealand. He was on a committee which set standards for children's television. And in later life he wrote stories for children, designed not only to entertain but to raise their awareness of other dimensions.
Since his death, he has made his presence felt in various ways to a number of friends and family members. It's no great surprise that he gave one of them to understand that he is now engaged in helping young people. She thought he meant helping youngsters who die to cross over without trauma or confusion.
I can imagine that they would find his kind smile reassuring!
