I drink my coffee and ignore the menu, surreptitiously inspecting the faces of my fellow diners, weighing the relative melancholy in each of their eyes, the shell-shocked expressions. An old couple murmuring to each other, bent over their soup bowls. A girl, nineteen maybe, with an enervated stare, joggling a pallid baby on her knee. A fat businessman glaring angrily at the menu, a cigar clenched in the corner of his mouth.
