"On the Mountain Holiday Thinking of My Brothers in Shan-tung" (九月九日忆山东兄弟), trans. Witter Bynner
Variant translation:
To be a stranger in a strange land:
Whenever one feasts, one thinks of one's brother twice as much as before.
There where my brother far away is ascending,
The dogwood is flowering, and a man is missed.

“They give up trusting others, and conversely others give up trusting them.”
"Our Inner Ape: A Leading Primatologist Explains Why We Are Who We Are" (2005), p. 243
Context: In 1879, American economist Francis Walker tried to explain why members of his profession were in such "bad odor amongst real people". He blamed it on their inability to understand why human behavior fails to comply with economic theory. We do not always act the way economists think we should, mainly because we're both less selfish and less rational than economists think we are. Economists are being indoctrinated into a cardboard version of human nature, which they hold true to such a degree that their own behavior has begun to resemble it. Psychological tests have shown that economics majors are more egoistic than the average college student. Exposure in class after class to the capitalist self-interest model apparently kills off whatever prosocial tendencies these students have to begin with. They give up trusting others, and conversely others give up trusting them. Hence the bad odor.
