have you done any act of defiance against informal norms?

-using forks to eat rice [coming from asian culture. spoons or chopsticks are norm]
-using green or purple pens in a class
-using a friction pen in exams [not sure if its acceptable though]
-being different and unique, Prideful of one's individuality
-wearing extra accessories when required to wear uniform to feel different from others
-taking the front seat of any class [even if i'm a bit of a slacker at times]
-refusing to do the Gangnam Style when all was doing it
-not going to parties and clubs during adolescence [even though that was the norm]

WHAT'S YOURS?
