We sleep with it, eat with it, panic if it goes missing for even five minutes. Let's face it—our smartphones are practically family. But the moment a shiny new model arrives? The old one gets ghosted, tossed in a drawer to gather dust. Love at first swipe, forgotten at first upgrade. So why is it so hard to recycle our old friend? 我们睡觉时带着它，吃饭时用着它，哪怕它消失五分钟都会让我们惊慌失措。说实话，我们的智能手机简直就像家人一样。但是一旦有款新机型闪亮登场？旧手机就被抛弃了，被扔进抽屉里积灰。初次滑动屏幕时一见钟情，初次升级时就弃之不顾。那么，为什么我们很难回收利用这位老朋友呢？
