Love in Afghanistan, pleas read this beautiful article by Rod Nordland in NYT:

“She is his Juliet and he is her Romeo, and her family has threatened to kill them both.
Zakia is 18 and Mohammad Ali is 21, both the children of farmers in this remote mountain province. If they could manage to get together, they would make a striking couple.
She dresses colorfully, a pink head scarf with her orange sweater, and collapses into giggles talking about him. He is a bit of a dandy, with a mop of upswept black hair, a white silk scarf and a hole in the side of his saddle-toned leather shoes. Both have eyes nearly the same shade, a startling amber.
They have never been alone in a room together, but they have publicly declared their love for each other and their intention to marry despite their different ethnicities and sects. That was enough to make them outcasts, they said, marked for death for dishonoring their families — especially hers.”

Perhaps the most effective way to solve this problem is to give these two people visas for the US or Europe. Afghan society may change one day, but they cannot wait for that to happen.
