I am a very introverted person. I'm not good at communicating with people. I'm plain, and I won't joke with others. I am lifeless. I work in Wallace and watch my colleagues play ball.

Read more cold jokes and humorous books, and chat with friends around you when you are free. When everyone laughs, you blend in. Are you serious or not confident? If you are serious, you should read more books about cold jokes and humor. For example, now the hospital always sends out some books, and then the last page of the book has a paragraph. I feel funny after reading it, so I try to tell it to the people next to me.
