I remember visiting one of Peter’s sister in law, must have been Alan's wife I think. She moved to Great South Road in Manurewa to a unit, would've been when my children were at primary school and we were living in Papatoetoe. Peter’s wife Betty was a good letter writer and suggested I go and see her.
