not my circus, not my monkeys字面意思不是我的马戏团，不是我的猴子，而是不是我的难题；这不是我的问题。

【例句】
He asked me to bail him out, but it’s not my circus, not my monkeys.
他让我保释他，但这不是我的问题。

He is always up to some monkey business. One of these days he will be caught with his pants down. Why should I care though, not my circus, not my monkeys.
他老是偷鸡摸狗的，总有一天他会被抓个正着。 但我为什么要在乎？ 又不关我事。
