This is a good way to judge a girl's mind. If she is extroverted, she may simply regard you as a good friend and buddy. Boyfriend and girlfriend are not popular now. She treats you as a relative and tells everything. Another possibility is that she likes you, has a good impression on you, pays special attention to you and has many hobbies with you. But these are small things, mainly depending on what you think in your heart. How do you feel about that girl? If you like her, go to the couple's side, if you don't like her, it's friendship.
