柠檬不酸为何心酸薄荷不凉为何心凉
[níng méng bù suān wéi hé xīn suān bó hé bù liáng wéi hé xīn liáng]
Translated as 'Why does the lemon not being sour make my heart feel sour? Why does the mint not being cold make my heart feel cold?', this implies feelings of envy and disappointment where one might expect something refreshing or pleasing but instead feels disappointed.
