Whenever I share with the people around me that I am an introvert, they think that I am lying.
I appear to be sociable and easy going seems to be able to make friends where ever I go. However, I really really have to mention this "it is just an ILLUSION!"
I agree that I make friends easily but the challenge is staying in contact and maintaining friendship. I would say that I have lots of acquaintance but few friends.
I believe that most of my friends does not even know my personal thought and feeling. I share about almost everything with them but not my personal thoughts.
