Describe things that don't belong to me. I don't want what belongs to me.

You won't ask for something that doesn't belong to you. Because this thing doesn't belong to you, even if you want it, you should return it to others in the same amount. After all, what you owe others is a matter of conscience.

What belongs to you, of course, must be owned by yourself. No one can take it away without your permission. This is what you should guard or mark your belonging. You can be rude to others if they want to snatch the past by force. Therefore, although this sentence is a bit domineering, it is also very reasonable.
