REALLY it is a common disease. hurries, worries and curries are the causes of anger also. i have seen the the journey specially daily visitors feels anger, tension and up set their moods when the train is getting slight late, no signals, slow speed ed and not running in time, like wise in peak hours of the offices the red signals irritate them, faster driving and some time safe drivers take time and some road accidents occur create anger, irritations, is ideal way to think on the road that we are dependent,no thing is in our control, and every individual is free and the buses, trains even own vehicle will takeits own time.  it is also routine of life so pass your time peacefully and planned your journey so you can make up your time .
