I had a flashback the other day when I was looking at photographs from Haiti of 15-year-old Fabianne Geismar, shot dead in the head after stealing wall hangings from a Port-au-Prince store, crushed in the Jan. 12 earthquake.

The image of Fabianne sprawled on the ground, blood trailing over the paintings she'd grabbed, took me back to my own childhood in Nairobi and the sight of a 7- or 8-year-old-boy - probably the same age as me at the time - who was caught stealing sweets from a street vendor and was beaten and burnt with rubber tyres. They called it mob justice.

To this day, I'll never understand why that poor boy had to die such a violent and senseless death for something so trivial. I feel the same way about Fabianne - she survived one of the most catastrophic events in living memory, only to be shot in the head for petty theft. And for stealing wall hangings where there are no walls.

Fabianne’s childhood was brutally stolen from her and it got me thinking about how quickly so many young people in places like Africa, Asia and the Americas have to grow up, forced to fend for themselves through child labour or prostitution, denied an education and exposed to violence, disease and hunger at an age when they should be learning and playing.

Of the 2.2 billion children in the world, 1 billion live in poverty and experience violence annually, UNICEF figures show, meaning nearly half the children in the world don’t get to have childhoods. There are also an estimated 132 million orphans in the world, UNICEF says.
