对不起我只是个孩子
[duì bù qĭ wŏ zhĭ shì gè hái zi]
Directly translated as 'Sorry, I'm Just a Child'. In China, people might take it as the individual trying to avoid responsibilities under the disguise of childishness, but on another level, it could mean that they are being truthful about immaturity or seeking leniency from others when facing failure or misunderstanding.
