One late evening, a woman reached home and after settling down, began rummaging through her bag. She realised that she did not have her mobile phone with her and did not remember when she had last used it. Thinking that she had misplaced it, she picked up her home phone and dialled her own number. Someone picked up the phone but she couldn’t hear anyone on the other side, except for heavy breathing. The woman asked, “Can you hear me?” A voice at the other end said, “I hear you.” She kept trying but to no avail. The woman then decided to go to sleep. When she entered her bedroom, she saw her mobile phone on the nightstand. When she checked it, it was on “silent” mode.
