Outside his office my father had a framed copy of a letter written by Abraham Lincoln to his son's teacher, translated into Pashto. It is a very beautiful letter, full of good advice. Teach him, if you can, the wonder of books...But also give him quiet time to ponder the eternal mystery of birds in the sky, bees in the sun, and the flowers on a green hillside, it says. Teach him it is far more honorable to fail than to cheat.
