Basic courtesy
It's basic courtesy to say hello. Don't forget to express your gratitude orally or in writing when you get help from others. If you have caused inconvenience to others, you should apologize sincerely at once.
Trust and frankness
If you don't want to tell one of your parents a secret, you can choose to trust the other. But remember, you can't hide it both ways. Honesty is the cornerstone of building trust. Lying will make you lose the trust of your relatives and friends and cause irreparable consequences.
Respect and judgment
When facing the collective and authority, we should respect and listen to their opinions. But you should have your own persistence and judgment in your heart.
Protect yourself
In case of danger or necessary situation, protecting your own safety is the primary task. You can call for help, you can defend yourself, you can ask for help. At this moment, any rules and constraints can be temporarily put down, because your life safety is more important than anything else.
