Yes, the very reason we have children as I now understand is to face death of our loved ones when the day comes, not 接代传宗，人类繁衍，抑或三代同堂。Rather, it is to confront the inevitability of death of your loved ones, particularly your parents.

In some sense, your children are part of your parents. In other sense, they are your parents, and they can't just sever ties with you as others might, cause it is the same blood that flows through your veins.

So when your parents eventually pass away, you know that you are related in this world, that you are not alone in this life.

Thus you can continue living, till your inevitability arrives.

But what if your children die before you, then how would you keep living?

I guess you will have to linger in this world as if it is limbo then, talk to humanity as if you don’t understand their language and they don’t understand yours, like an outsider in every country, a truly nowhere man, adrift, just like Lee, till your day comes.

Don't really know, man. I really don’t, neither does this movie "Manchester by the Sea".
