One of them, artist Marina Abramovic, was putting on a live art performance at the Museum of Modern Art which involved complete strangers sitting opposite her whilst they stared into each others eyes. Unknown to her however her ex boyfriend was in the crowd. When she first looks up and realises who it is sitting in front of her, they are both overcome with emotion and you will be too.
