Mr. A never threw anything away.  

His repair shop was a museum of forgotten technology—televisions with rabbit-ear antennas, rotary phones with frayed cords, and one very peculiar computer mouse from 1998.  

It was an ugly thing, beige and boxy, with a rubber ball underneath that hadn’t rolled in decades. But when the college kids laughed at it, Mr. A would plug it in and say, "Wait for the click."  

 The Double-Click  

One rainy afternoon, a programmer named Neha brought in a sleek wireless mouse. "This old thing still works?" she scoffed, nudging the relic.  

Mr. A pressed the left button.  

Click.  

The shop’s lights flickered. Neha’s modern mouse suddenly died.  

Click.  

Every screen in the shop lit up—not with error messages, but with green lines of code no one had typed. A DOS prompt blinked:  

>  HELLO, OLD FRIEND.  

 The Ghost in the Machine  

The beige mouse trembled like a waking dog. Its scroll wheel spun wildly as pixelated memories flooded the monitors:  

- A teenager in 1999, writing his first "Hello World" program  
- A weeping man deleting wedding photos in 2008  
- A little girl in 2015, dragging this very mouse to defeat a digital dragon  

Neha gasped. "It remembers every hand that ever held it."  

 The Final Input  

Mr. A gently unplugged the mouse. The screens went dark.  

"Some devices don’t just process data," he said, wrapping it in a handkerchief. "They process time."  

That night, Neha returned secretly and stole the mouse.  

But in her high-rise office, it refused to work. Until she whispered:  

"Thank you."
