People are different. Some are _ . These people are outgoing, confident, and know the "gift of the gab". They also feel very comfortable when in groups of people. Unfortunately we have the other extreme. This is the introvert. The introvert feels sick in crowds, and does not like them. These people feel awkward in the crowds, when placed in this type of situation. Many introverts are shy and lack confidence. They need to get used to people, and want to run away when questioned by people. The introvert feels very lonely in a crowd, but this could happen to the outgoing  as well. I think that I fall into the middle of the two kinds. Sometimes if I am comfortable about the type of people in the crowds, I feel welcome. If for some reason the crowd consists of different types of people, then I do not feel very comfortable in the crowd. So what do I do when I suddenly feel lost and alone in the crowd? I try to calm my mind by taking deep breath and telling myself that even this will pass. I then try, and get away from the crowd by making excuses or even trying to get to my car and go home. This, of course, is a poor excuse and doesn't often work well. These are excuses that are employed. The ones that I am not so proud of are acting like I have an emergency to go to. This is a very good lie, but I feel really bad afterwards. I have tried this one, and have succeeded. I try and find someone who feels just like I do. I then try and make a new friend. Sometimes this works and sometimes it does not. This is quite a noble way of staying in the crowd. The word "extrovert" is most likely to mean   _  .
