In a fleeting encounter, his game of marbles attracted Diana's attention and made a memory that lasted a lifetime.
The simple things in life can sometimes lead to the most wondrous experiences.
It was a handful of glass marbles that drew the attention of the most famous woman in the world to a star-struck Auckland boy.
David - now known as Dave - Fisher was kneeling in the grassas the royal entourage of Princess Diana and Prince Charles were led around Eden Park, at the start of their 1983 tour.
Schools from around Auckland had children stationed in small gatherings for their HRHs to peer at and chat to. Fisher was with schoolmates from St Joseph's of Orakei.
Suddenly however, there she was. In an emerald green dress with stripes and spots, white hat, stockings and shoes, a pearl necklace and earrings.
"She asked me what I was doing," Fisher says. "And I said I was playing marbles."
And that was it. Fisher's recollection of meeting Diana.
"I'm still very fond of that memory," he says.
Now a lighting production contractor, Fisher says he was extremely saddened when Diana died in August 1997.
All the more so as he recalled soft words spoken from a woman who once crouched to the level of a kneeling schoolboy to ask one of the simplest of things.
