我姓董却永远不懂你的心
[wŏ xìng dŏng què yŏng yuăn bù dŏng nĭ de xīn]
'Wo Xing Dong Que Yong Yuan Bu Dong Ni De Xin' directly translates to 'I am surnamed Dong but forever fail to understand your heart/mind/feelings.' This implies the holder acknowledges their lack of understanding or inability to empathize with someone closely.
