No, not the title of an obscure art-house movie. I was giving a guitar lesson to an Afghan friend yesterday, and advising him to cut the nails on the fingers of his left hand. I told him that a number of people in England believe for obscure superstitious reasons that you shouldn't cut your nails on Sunday, and I wondered if there was any similar belief in Afghanistan. He laughed a lot, and said that surprisingly enough he had exactly the same belief, except that in Afghanistan it's Friday. Interesting, huh??
