There are two people on the Zoom screen in front of me. One, a Palestinian man in the ancient city of Jericho in the West Bank. The other, an Israeli woman in Tel Aviv. They're separated, literally and metaphorically, by a wall. And they're united in loss: specifically, the loss of a child. Something else unites them: a determination to build bridges of shared understanding at a time when the gulf between their peoples seems deeper than ever. They're both part of the Parents Circle Families Forum (PCFF), membership of which has the grimmest of qualifications: that your child has been killed in the conflict. Their backgrounds could not be more different, and yet, partly because of their loss, they've arrived in the same place. The fighting has to end, and bereaved parents are better placed than most to achieve that. "Before you start to talk [in those meetings]," says [parent Bassam] Aramin, "you can see in their eyes the fear " even hatred " for this Arab, this 'terrorist'. And after you finish your human story, suddenly there is no fear. Suddenly there is empathy. Some of them cry. Some of them want to shake your hand. This is, as Robi always calls it, our 'emotional breakthrough'." 'Robi' is Robi Damelin, now director of international relations for the PCFF. Born and raised in a comfortable home in South Africa, she followed in a family tradition " her uncle had helped defend Mandela in his first treason trial " by speaking out against apartheid.
