I’m sitting opposite a man. I don’t know where he lives or what he does for a living. I don’t even know his name or age. But I do know what’s in his heart. He’s speaking, painfully honestly, about the collapse of his marriage, about his fears for his children, about his loneliness. Tears well up, firstly in his eyes and then in mine. We’ve jumped right past the usual social niceties and it’s smashing my heart wide open. I’m at the first Togetherness Festival in London.
