The Silent Signal
In a quiet little town in England,there lived an elderly man named Harold.Uneducated and widowed(鳏夫),Harold's heart was heavy with loneliness.His children,Emily,a doctor in London,and Thomas,a lawyer in Manchester,had moved to the busy cities,leaving him in the family home with only his old mobile phone for company.The phone was a lifeline to his children,and he treasured every ring.
One day,Harold decided to visit a local mobile phone repair shop,TechSolutions,with a sense of urgency.His phone,an outdated one,had been silent for weeks.No calls,no messages﹣just a terrible quiet that seemed to mirror his life.
Harold entered the shop,with his pace slow and tired.He approached the counter and handed his phone to the young repairman,a cheerful man named Liam."There's something wrong with it,"Harold insisted,his voice trembling slightly."It's not ringing,and I'm sure my children,Emily and Thomas,want to speak to me."
Liam,with a warm smile,took the phone and began to inspect it.Harold watched and held his breath as Liam pressed buttons and shook his head,saying technical terms under his breath.After a few minutes,Liam looked up and announced,"Everything seems to be in order,Mr.Harold.Your phone is functioning perfectly."The news did not bring relief to Harold's wrinkled forehead.If anything,his worry lines deepened."But if it's working,why haven't I received any calls?"he asked,his voice barely above a whisper.
