I wasn't quite a terror (that was my brother), but I certainly had my share of naughty days. I got in trouble at school at lot, mostly for talking too much (I've been called gabby), being too loud, not doing my homework, talking back to or challenging my teachers, and occasionally swearing. Being sent to the corner or hallway was always a treat. [I entertained myself well, often dancing .] I was sent to the principal's office a number of times. Once I waged a complaint against my third grade teacher, when sent. Another time I got the paddle (was still given in 1970s Pennsylvania). Other times, after school or weekend detention.

Like Yaowen, my mood did have some fluctuations. I also had periods of great anxiety, depression and despair, and anger. Won't go into that other than to say that the school told my parents to send me to a private school, which they did.

At university I was fine, but turned into the student in the class that raised her hand all of the time, with all of the answers. I remember once telling myself "Soupe, don't raise your hand! The other students are probably sick and tired of you!" Then, of course, no one would answer the professor's question. So.... He looked straight at me and asked:

"Soupe... What do you think?"

A rush of relief like a tidalwave then came over me, then I answered, gleefully. He had mercy on me. Thank you, thank you, 谢谢 Professor Li!

I do think my bipolar disorder played some part in the above, fairly early on. However, I also think nature and nurture played a part. Many in my family are similar, with just a few exceptions.
