何必费心记得你
[hé bì fèi xīn jì dé nĭ]
Translating to 'Why bother trying to remember you,' it suggests a sentiment of moving on. This could express someone letting go of the past (a person, event) because keeping memories no longer holds value or meaning. It reflects an attitude where someone believes putting effort into remembering another person is unnecessary, perhaps indicating closure or apathy.
