Ali and Sanaubar had little in common, least of all their respective appearances. While Sanaubar's brilliant green eyes and impish face had, rumor has it, tempted countless men into sin, Ali had a congenital paralysis of his lower facial muscles, a condition that rendered him unable to smile and left him perpetually grim-faced. It was an odd thing to see the stone-faced Ali happy, or sad, because only his slanted brown eyes glinted with a smile or welled with sorrow. People say that eyes are windows to the soul. Never was that more true than with Ali, who could only reveal himself through his eyes. I have heard that Sanaubar's suggestive stride and oscillating hips sent men to reveries of infidelity.
