原谅我一生薄情寡义假洒脱
[yuán liàng wŏ yī shēng bó qíng guă yì jiă să tuō]
Roughly translated as 'Forgive me for my lifelong insensitivity, indifference, and pretended detachment.' It might mean that the person wants others' understanding and forgiveness on how they behave all along in a dispassionate, aloof, and apparently liberated way.
