Yeah, I've been once to all day detention. It was during the last weeks of middle school in 8th grade and we had to write a story for English. She said we could write whatever we wanted in our group and just to be creative. Well, I had a very creative mind back then and I wrote about some questionable things. The main parts of the story features things like kidnapping, teachers, schools, guerrilla warfare, taking the budget for the school and buying nuclear weapons, etc. Needless to say, the VP wasn't impressed and he told me to go to all day detention for it (along with everyone else)
He called home and told my mom, she didn't understand at all considering it was creative writing, not some threat or anything. That was the only time in my entire life I ever was disciplined in school. I did nothing in that room the entire day. In some ways it was a lot better than being in class, you didn't have to learn anything and you could just zone out. FK school administrators and their retarded policies.
