Chances are you haven’t heard the whole story. The most basic definition of an introvert is a person who gains energy from being alone and loses energy in stimulating environments, such as social events (people are very stimulating, by the way). But there is much more to it than that.
Some introverted traits seem to be ingrained. Others are a result of the culture we live in. For example, many introverts have learned to cope with constant overstimulation by putting up a wall. This leads people to believe that introverts are cold, or standoffish, but this is not our true nature. The innate qualities that most introverts share are a love of introspection, a need for solitude, and a slower, more focused communication style.
