Today I was travelling by a packed suburban train.I could barely keep standing with no possibility of any movement. In such a situation the fellow in front of me heard his mobile ringing. With great difficulty he reached for his mobile and managed to fish it out in the crowd and receive the call.
The call was a wrong number. Unfortunately for him the call was repeated again within five minutes and again the wrong number.
Then he switched off the phone and waited patiently for his station to come.
