In our society, there are numerous categories that help define a person. When asked about an individual, it is easy to describe them by choosing a collection of these such as race or gender. While these groupings can be somewhat hurtful, they are mostly helpful in creating unity or learning more about ourselves. One of the more controversial labels are those that describe our interactions with the world. The word introvert describes those who gain energy from within, while extrovert describes those who gain energy from the outside world. Neither type is better than the other, and both embody a similar relationship as yin and yang. Of course, these types are stereotyped in various forms of media. Anime does a pretty good job of portraying them in a more positive and realistic light, but there are still mishaps. These generalizations stem from common traits, hobbies, and other basic characteristics of an individual that are usually unrelated to an outer or inner personality.
