英语中有个十分形象地道的表达，“be/live in each other's pockets”，表示“形影不离”。按字面理解，“pocket”表示“口袋”，“住在对方的口袋里”，亲密程度可见一斑，形容“过从甚密；形影不离”。比如，班主任见你跟班里谁谁谁走得太近了，唠叨一句“I don't think it's good the way you two are always in each other's pockets.”，是说“我觉得你俩老是形影不离，这样不太好”。嗯，距离产生美。
例句：They have such a close relationship that they seem to live in each other’s pockets.
他们关系太好了，貌似每天都黏在一起。
Being in a relationship doesn't mean you have to live in each other's pockets.
恋爱了并不意味着你们要形影不离。
类似短语：
inseparable形影不离
be joined at the hip形影不离
out of pocket没钱了
the eight-ball in the corner pocket球袋里的八号球，指大功告成前或事情完成前的最后一步。用于快要完成某事的时候，表达对完成充满期待以及如释重负之情。
