It goes either way, depending on circumstances. For example, if someone has a new lover, the adulterer usually moves out.

You have more important things to be doing right now than hang out on HN. Take care of your baby, take care of your wife, and sleep when you have a moment off from those.

Commitment and accountability to the person how bears your children, or who supports you through medical school or your startup years, has everything to do with a piece of paper filed with the local government.
On the one hand, compared to Amazon.com, Taobao sounds like a horrible shopping experience. On the other hand, compared to a shuk (or whatever the Chinese equivalent is), it is a vast improvement.
I had this problem. My parents never talked to me about how much things cost. I had a rude awakening when I learned how much basic rent was, even more so when I learned what my rent was when I was a kid.
My kids will know how much their stuff costs, and they will earn their luxuries.
