哀家旳温柔曾喂过狗
[āi jiā dì wēn róu céng wèi guò gŏu]
Loosely translated into: 'The Kindness Which I Showed Was Given to Dogs,' it comes from disappointment in treating some people kindly but getting hurt in return. Thus, using a humorous and self-satirical tone to make a statement, it means they once trusted people too easily, leading to their being deceived.
