I was pritty much a class clown/badly behaved student down to a tee. I was threatened with expulsion every year from year 8 (im in the uk) till year 13. I prposely pissed off teachers, teaching assistants, dinner staff, caretakers; basically very member of staff at both schools i went to. I was imature and hyperactive, lodes of the teachers thought i was either on drugs or had adhd, I just was completely unable to calm down once i was excited.
Socially it worked for me, other students found it entertaining (a few found it unbelieveable annoying of course),but never got expelled because I was top of most of my classes and so good for school ratings. I've calmed down dramatically now, rarelly get those lovelly moments of hyperactivity-I sometimes miss it-but it's all for the best. Still, never have been diagnosed with adhd, already got to many labels to bother myself with that one aswel. But yeah, fun times
