原谅我冷漠无情是个烂人原谅我无理取闹是个疯子
[yuán liàng wŏ lĕng mò wú qíng shì gè làn rén yuán liàng wŏ wú lĭ qŭ nào shì gè fēng zi]
This translates as 'Forgive my apathy, being heartless, an immoral person; forgive my unreasonable temper, being a lunatic'. It reflects feelings of regret and self-deprecation, perhaps from guilt over actions taken in the past.
