It was scarcely worth noticing at first; an out-of-work lying under one of the rare indigenous shrubs cultivated by the Botany Department on the campus. Some of us remembered, afterwards, having passed him. And he – or another like him – was seen rummaging in the refuse bins behind the Student Union; one of us (a girl, of course) thrust out awkwardly to him a pitta she’d just bought for herself at the canteen, and she flushed with humiliation as he turned away mumbling. When there were more of them, the woman in charge of catering came out with a kitchen hand in a blood-streaked apron to chase them off like a band of marauding monkeys.

We were accustomed to seeing them panhandling in the streets of the city near the university and gathered in this vacant lot or that, clandestine with only one secret mission, to beg enough to buy another bottle; moving on as the Druids’ circle of their boxes and bits of board spread on the ground round the ashes of their trash fires was cleared for the erection of postmodern office blocks. We all knew the one who waved cars into empty parking bays. We’d all been confronted, as we crossed the road or waited at the traffic lights, idling in our minds as the engine of the jalopy idles, by the one who held up a piece of cardboard with a message running out of space at the edges: no job im hungry everyone help pleas.

At first; yes, there were already a few of them about. They must have drifted in by the old, unfrequented entrance down near the tennis-courts, where the security fence was not yet completed. And if they were not come upon, there were the signs: trampled spaces in the bushes, empty bottles, a single split shoe with a sole like a lolling tongue. No doubt they had been chased out by a patrolling security guard. No student, at that stage, would have bothered to report the harmless presence; those of us who had cars might have been more careful than usual to leave no sweaters or radios visible through the locked windows. We followed our familiar rabbit-runs from the lecture rooms and laboratories back, forth and around campus, between residences, libraries, Student Union and swimming-pool, through avenues of posters making announcements of debates and sports events, discos and rap sessions, the meetings of Muslim, Christian or Jewish brotherhoods, gay or feminist sisterhoods, with the same lack of attention to all but the ones we’d put up ourselves.
