I got to give out my first two detentions today. One guy threw something at a guy across the room, who then proceeded to throw it back. I also got to tell a whole bunch of students that they couldn't turn in Friday's test today. This was not a take-home test, even though we did go out and about to complete it. No, this was an ordinary, due-at-the-end-of-the-period test. I reminded them to turn it in, but one of my classes apparently wasn't listening (I didn't have any problems with the other class).
This whole thing makes me wonder if these kids have been paying any attention in school. They're 9th graders! They've got lots of experience in the classroom. None of this should come as a surprise.
