Below is a picture of the West Bank barrier, photo taken from the Palestinian side. That is Israel on the other side. You'll some some red script on the 8-foot high concrete wall. That is my present. Look closer.
The reason for messages on the wall is as follows, "You help to keep hope alive. 'Our' Palestinians want to send you one single, simple message: "we are human beings, just like you, with sense of humour and lust for life." That's why they do this, and enjoy it."
This is the young gentleman who left the message.
