Incorrigible

Yesterday, before going home, I had to stop by the Post Office. This took me past a school where young people, who have been expelled from other public school, attend. I notice none has any books, a notebook or even a book bag. Obviously these young people had not committed a crime, or they would be in the detention center, but now they were going to this school. What I didn't understand is why they would come to school on their own, taking the bus or walking, and not be interested in anything. They're wearing uniforms, in a public school it is not mandatory. I am not saying they are not coerced in some way, but if they were really incorrigible, would they not go to school, coercion or not. Could it be that they are just warehoused during school hours and nothing is expected? If something was expected, there would be homework and a least a few probably would have books, a notebook or a book bag. That is what I came to believe, seeing all those young people leaving school.
