Usually I am an unsociable person, and I don't like to make friends on my own initiative. What kind of mentality is this?
This shows that you are a quiet and passive person, and this mentality is not bad, because everyone's personality is different, so all this comes from personal choice. Maybe you think it is more convenient to be alone, and it is difficult for you to make friends on your own initiative, so you are more inclined to choose one person.
