If there is a girl, change her QQ signature frequently and often make a talk about herself. Tell me what her psychology is.

It means that she can't find a good friend to talk to without thinking about it. She is a very empty person. She has been saying one thing: no one can communicate in reality, and second, she doesn't have the courage to face each other on the internet, so she won't be timid. And talking often can attract others' attention and prove her sense of existence. She needs a good best friend?
