Deviance

From a young age we are all taught to respect our elders, listen to authority figures, and we seem to develop a sense of what our culture determines as "normal." However, when we all took a survey about what we think is deviant, everyone in our class had different answers. How is it that something that seems so important to our culture can be so subjective? If I don't agree with a majority of society, all of the sudden I'm deviant? This does not seem to support that there can ever truly be "normal," just more popular. Furthermore, deviance is only sometimes considered deviant in some cultures; there is no universal standard unit of measurement for deviance.
It seems funny how even the littlest things can be deviant. In my house, I was always taught that when I finished my meal I pick up my dishes and bring them to the sink. I ate at a friend's house this weekend and when I cleared my spot, his mother looked at me with shock. She then continued to look at my friend in a, 'how come you never do that?' kind of way. Even though this seemed like a normal, polite thing to do, it was deviant because it did not follow the accepted norm of the household I was in.
