When the cornerboys saw that no one was coming out, they pelted the dorm with rocks and broke windows. They shouted that if no one came outdoors, they were going in. A cornerboy who wore a headband threw what looked like a lead pipe.

The buyer walks past the old men at the lot, the family on the stoop, to the cornerboys, as I thought.

Father O’Flaherty taught Irish, or, to be more precise, spoke Irish with the country boys who already knew the language and insulted, cuffed and punched the contemptible town cornerboys who knew only English. If a cornerboy made an especially grotesque mistake, as often happened, Flah took the soft flesh of the boy’s cheek between his finger and thumb, violently shook the boy’s head till he gurgled, roared in disgust, ‘Are ye goin’ to give us yer breakfast, ye slabber?’ and slammed the head into the partition (the classroom was part of a prefabricated hut divided by wooden partitions).

‘I haven’t had time to get to know you all yet – but mark my words – I’ll remember you two – I’ve never seen such a display – rolling in the earth like cornerboys.’ I had no clue what a cornerboy was, and Beth and I hadn’t been rolling around on the earth anyway, but it didn’t look like Mrs Gallagher was up for a reasonable debate.
