These Palestinian children walk alongside a river of blood on their way to who knows where but probably to school or home again.
The blood was provided without charge by several Palestinian men shot and killed by the occupying Israeli Defence Forces. Such rivers are commonplace in the Palestinian Territories. The children are unmoved. They've seen it all before. And much worse.
When I went to school, a five kilometre walk, I used to collect empty cigarette packets thrown from cars and make them into thin cards. At school, with other boys, you'd flick them through the air and the card which landed closest to the wall was the winner and its owner collected all the other cards. I never walked alongside blood.
On my way to school or going home, if a friend joined me, we would often play glass marbles. It made walking fun. If you hit the other person's marble then it was yours. Some of the marbles did have swirls of red in them but they never bled.
Of course if it was raining, the gutters provided all manner of fun for those like me who had bare feet. Twig boats were launched and races were held. Dams were made from large stones. But the only thing that flowed down the gutters was clean water.
The local cinema was a great place to go past. Often bits of film would lay on the ground and when you discovered one you held it up and looked in amazement at the tiny, perfect, romantic images captured on the soft strip. Don't ever recall seeing anything threatening there.
The ice works was another place that was great to go by on a hot day. Sometimes you could nick a bit of ice and suck on it the rest of the way home. One day, while reaching in under the table saw where the blocks of ice were cut, I hit my head on the stationary saw. My head bled a bit and a few drops fell to the ground.
It was the only blood I saw during my entire childhood while walking to and from school. Guess I was lucky!
Some children aren't.
