成年后还跟父母住一起的：大多是低知和低能的孩子。

On a Chairman round during residency, a medical resident reported a case:
A 30 years old man, who is living with his parents, presented with ..........
The chairman says: stop here, the guy is 30 years old, still lives with
his parent, must be a loser!

We often see patients who are adults living with parents, most of them are
losers: do not have good education, and are drug user and jobless.

Traditionally American seeks for individual independence. Good individuals
usually do not live with parents!

When we asked our kid: welcome to home live with us, you will save money
for the rent and foods, who answered: do you want me  to be a loser?!

但是，每次打电话给我妈，她老抱怨说：一家人住两个地方，哪有国内一家人住在
一起热闹？!
