对不起我不善良
[duì bù qĭ wŏ bù shàn liáng]
'Sorry, I'm not good-hearted'. This straightforward statement acknowledges the imperfection in human nature. Sometimes people use it to admit personal weaknesses or flaws, or they're unwilling to always be forgiving, patient or tolerant in interpersonal relationships. A slightly cynical way to express individuality.
