承诺就是说给傻子听的
[chéng nuò jiù shì shuō jĭ shă zi tīng de]
This translates to: 'A promise is made only for fools'. It shows the user's cynicism toward making promises, possibly stemming from bitter life experience of false promises or unfulfilled words. He may have realized that some people do not keep commitments which leaves those who truly believe these empty words heartbroken.
