Samooborona by Israel Zangwill

But his way was blocked by a turbulent stream of Jewish boys pouring out of the primary school. They seemed to range in years between eight and twelve, but even the youngest face wore a stamp of age, and though the air vibrated with the multiplex chatter which accompanies the exodus of cramped and muted pupils, the normal elements of joyousness, of horse-play, of individual freakishness, were absent. It was a common agitation that loosed all these little tongues and set all these little ears listening to the passionate harangues of ringleaders. Instead of hurrying home, the schoolboys lingered in knots round their favourite orators. A premature gravity furrowed all the childish foreheads.

With one of these orators David dimly felt familiar, and after listening for a few minutes to the lad's tirade against the 'autocracy of the school director' and the 'bureaucratic methods of the inspector,' it dawned upon him that the little demagogue was his own landlord's son.
