Well, I can't say I really do.
I act more quiet in real life, because most of my class are materialistic, dumb brats. However, I am obliged to act like I like them for my own personal gain. (School reputation etc.). I also never share my views on religion, because last time I did, I was kicked out of the class by my teacher..
However, I act like I do here with my best friends and/or close friends.
They all know that I am quite good with computers and some try to bribe me to hack their friends. (Yes, they are that stupid.)
I act mature around the mature ones and vice versa.
