The one called extrovert: loud and full of story. You can hear their words from hour to hour. Talking about their personal life, things they hate and love, boys, girls, all things in their mind. Those people are loveable. I like them. I know when they are angry, happy or even when they are heart broken. Most of them have confidence to show their feeling, doesn't matter if it's against the rule.
And then there is other people. It is unlike the first, sealed and unpredictable. The introvert. They are interesting in their own way, like a book which you hardly decide whether you like them or not. Somehow, they hide their feeling, behind an unseen curtain. They might tell you stories but you know, they keep their personal life in them.
I don't care which one you are, most people are interesting.
