How ought I to describe the appearance of a young boy garbed in orange? How might I convey the feeling generated by his distracted whistling? What manner of words might sufficiently depict the countenance of his young friend who, arm wrapped around him, studied the distant crowd? And how possibly to demonstrate the nervousness of the grandmother who passed by just at that moment, concealing strange goods under a cloth on her head? Or the peculiar aspects of gentleman behind them whose wily glance in the opposite direction provoked a certain sentiment for which the words elude me?
