有些事不用说出口你也明白有些人留与不留都不会回来
[yŏu xiē shì bù yòng shuō chū kŏu nĭ yĕ míng bái yŏu xiē rén liú yŭ bù liú dōu bù huì huí lái]
This translates to 'There are some things that don’t need to be spoken, and some people won't return whether they are kept or let go', meaning certain truths between people are intuitively known and that specific individuals are destined to leave, despite efforts to retain them.
