Whether it's reliable or not depends on the people you meet. I met a reliable and unreliable person before, and that kind of reliable person became good friends. After several years of contact, life changes will be related, and every once in a while, we will catch up like old friends and will not feel embarrassed. If you think the person you just met is unreliable, then don't contact him. The most important thing is to protect your privacy. Don't tell the whole story. You must protect yourself.
