离群索居

nà ge zì xìn de huǒ ji zǒng shì lí qún suǒ jū

那个自信的伙计总是离群索居。

That confident fellow always keeps himself to himself.

tā yǐ jīng lí qún suǒ jū èr shí duō nián duì wài bù shì jiè hěn mò shēng

他已经离群索居二十多年，对外部世界很陌生。

The life of a recluse for 20 years has made him a stranger to the outside world.

tā shì gè lí qún suǒ jū de rén gū dú de sǐ qù yě xǔ zhèng dé qí suǒ

他是个离群索居的人，孤独地死去也许正得其所。

A solitary man, it was perhaps fitting that he should have died alone.
