The Vietnamese word "cáo lão" refers to a situation where someone resigns from a position or responsibility, claiming that they are too old or advanced in age to continue. It can imply that the person is using their age as an excuse to step down, even if they might still be capable of performing their duties.
In more advanced discussions, "cáo lão" can be used to critique someone who is seen as avoiding responsibilities under the guise of age. It can also relate to discussions about the expectations of older individuals in the workplace and how age is perceived in terms of capability.
While "cáo lão" primarily refers to resigning under the pretense of advanced age, it can also be used metaphorically to describe any situation where a person avoids responsibility or accountability by claiming they are no longer fit for it.
