I have gotten in trouble for three things.
1.Being Bullied: In the 1st grade, I was on the bus with my friend, as we were leaving school. This fat 2nd grader decides it would be fun to not only sit on us, but slam our heads against the window so we couldn't breathe, and call us "stupid 1st graders".
Our bus driver grabbed him and I by our shirts and dragged us to the principals office, where we were told that we would report to his office during lunch the next day to resolve the situation.
I told my parents about this later that day, and they just said "we will take care of it".
The next day, take care of it they did. When I got to the office, my mother simply said "go back to lunch, we got this".
2.Reading: On Earth day in the 8th grade, my reading teacher brought us out by a group of trees to read. The kids sitting near me decide to have a rock fight with another group of kids. They got in trouble, but I was also accused with crime by association (I barely knew them).
Three days of In School Suspension later, and a perfect record tarnished, I never forgave the woman who did that.
3. Poking someone with a paperclip: In reading class in the 10th grade, I poked a kid who has been a massive prick since I met him, because he was sitting in my seat and wouldn't move, even when I asked him politely three times.
Our teacher was new, and this was the third day of school, so naturally, she decides to side with him when he claims I assaulted him by poking him with a paperclip.
