It seems as if the world is divided into two different groups of people. One of those groups tends to be outgoing and they seek other people so that they can interact with them. That group is known as extroverts. The other group is introverts and they tend to be shy and want to spend most or all of their time by themselves. Neither is right or wrong, they are just different personalities.
More than likely, you have an idea of which of those groups you fit into. What might come as a surprise to you, however, is that you are not always going to be correct in your assumptions.
