It would be difficulty to imagine modern life with the telephone. It has become a useful instrument of
communication, save much time and travel by enabling people to talk one another over great distances.
Nowadays it is so easy to talk cross a continent or even overseas as it is to talk to one's next-door neighbor.
Therefore, it is in emergencies which the telephone really proves its usefulness. When there is a fire, and
when someone is suddenly ill, the first thing one thinks of it is “ Where is the nearest telephone?”
