Tell me what to see.

1. Don't talk to people casually. In your opinion, she is a friend, but in her opinion, you are a fool.

2. Once, I thought that as long as I was sincere enough, others would be honest; As long as you work harder, you will be different. But it was later discovered that people's hearts are complicated and things are unpredictable. Not all people are kind, and not everything is as you wish.

People's eyes are parallel, but people are always unequal. People's ears are separated, but there is always a good side. Humans have only one mouth, but they can always tell the two sides.
