I got suspended once and I was not guilty of the offense I was accused of. It was during my junior year in high school. We had a half-day because it was the last day of school before Christmas vacation. Anyhow, we had homeroom, something called "activity period" which was a weekly period of time when you could work on whatever extracurricular stuff you were involved in (in my case it was hanging out in the computer lab because I was in the so-called computer club), and then there was an assembly. Well, as soon as the assembly was over, they dismissed the fresmmen and sophomores. Me and my buddies wanted to get back up to the computer lab to get back to what we were working on, so we split at that point. I was acutally in the computer lab until almost 4PM, which was 5 hours after school was dismissed. It turns out, they took roll of the juniors and seniors before dismissal from the assembly. The reason for this, was alot of people cut the assembly and went home at like 10AM. Apparently the principal/faculty noticed alot of people missing. Since many juniors and seniors drove, this was a relatively easy thing to do. You could cut and not have to worry about how you'd get home.
Two days into Christmas break, my parents get a letter from my school (complete with a nice Seasons Greetings postage stamp) saying that I cut school on such and such a date and was suspended upon my return to school after the break. Needless to say, my parents freaked. At the time, I had no clue what this was about. That made them even more pissed because they thought I was flat-out lying. I got to spend 2 weeks at home, grounded, with my parents yelling at me on a daily basis about it. I was able to clear it up once I got back to school after the break. I went to the discplinarian and basically asked him WTF this was about. He explained it to me. I then told that I did leave after the assembly with the underclassmen, but I went back up to the computer lab. He said if I could find a faculty member who could vouch for me, he would lift the suspension and call my parents for me. After a few seconds, I realized I had it covered. I went to look for my homeroom teacher. Luckily, he remembered seeing me at like 2PM on the day in question. I ran downstairs to grab a soda from the machine in the cafeteria. Luckily for me, I bumped into him on the way back up and we had like a 10 minute conversation. I dragged him to the disciplinarian's office and had him get me off the hook. I insisted at that point that he call my father at work to get me out of trouble on the parental front.
I can laugh about it now, but it really sucked when it happened.
It's ok, it kinda makes up for the stuff I did that I never got busted for.
