I want to talk to a stranger because I don't know. ...

It's normal to want to talk to strangers.

Because there are some things you can't tell your parents, and then you don't want to tell your friends, so you need to find someone who doesn't know you. In this way, I have no scruples, and then I can express my feelings, which is better than keeping them in my heart.

Because the stranger doesn't know you, what you say and do has nothing to do with him. Then he won't pass it on to others. Even what you said, he will give you an analysis. So it's good to have a stranger to chat with you.

Once you have something in your heart, you want someone to express it. Venting is also good for your mental health. If you don't tell anyone, you are sure to get sick.
