This was from someone who showed me the way he lived his life — someone who was fond of me, who shaped my early childhood, and who alone could instruct me in things no one else could, not even my own parents.

"When I am gone, contend not over the possessions I leave behind.
Heaven has bestowed upon each of us a complete provision: a mind to discern right from wrong, hands to labor, and feet to walk the Way.
This is abundance enough for one’s journey through life.
Hold fast to these gifts, fulfill your duty, and be content with Heaven’s allotment."

It is this very idea — 人情难还 — that reminds us what it means to be truly human.
If life continues without people showing kindness, without anyone repaying grace, and everyone living entirely independently — as we so often see in today’s world — then life begins to feel hollow.
When society loses its sense of 礼 — the spirit of mutual respect, moral duty, and heartfelt response — what remains is a cold, disconnected existence.
But 人情, when it flows naturally and sincerely, without being abused or exploited, is not a burden — it is a blessing.
It is one of the most beautiful aspects of being alive. It binds us to one another, gives meaning to our actions, and brings warmth to the human experience.

What does this have to do with open relationships? I do not find any correlation at all.

While I cannot control how you shape your way of thinking, I can only share my own perspective. If that way of thinking does not align with my principles in life, I do not have to adopt it. There is no need to impose it on others either as well.

If a person’s decision is good, the outcome will also be good. That decision may then serve as a teacher or role model to others. On the other hand, if the decision is bad, the outcome will be negative. That decision itself becomes a lesson for others to avoid.

As for your original question, since I have no personal interest in the matter, I will not respond directly. However, that does not stop me from making my own observations. I hope you are satisfied with this kind of reply.
