I too have thought about those who were repeatedly caned. Typically they were fairly high-spirited lads who enjoyed a prank – these days they might be described as “hyperactive” – I might prefer the word “mischievous”.
I don’t think they lacked intelligence but they tended not to be the top students, even so their lively characters gave them some status in the class. I have to admit I sometimes wished I was more like them because they made friends easily and seemed to have a lot of fun.
