一段友情离开了就淡了一段爱情分离了就散了
[yī duàn yŏu qíng lí kāi le jiù dàn le yī duàn ài qíng fēn lí le jiù sàn le]
'Friendships fade when they depart, loves scatter once parted.' This expresses how relationships can grow distant over time after separation due to changes in circumstances, locations, priorities or people drifting apart naturally, highlighting transient but poignant nature of human connections.
