There has been some times when i have been waiting for the bus somewhere in Helsinki or Espoo (city next to Helsinki in Finland) and all the passengers from that particular stop have already boarded the bus and the bus has been ready to take of. Then i have seen somebody appearing somewhere around the corner or up the hill etc. and very spontaneously without thinking too much i have raised my hand to stop the bus from leaving or gotten into the bus to inform the driver about some persons still coming onboard. This has happened perhaps three of four times in the last years. The people running have then not missed their bus. Not all the times her/him has really noticed what took place. I remember at least one time being thanked for this action. I felt really good afterwards and realized from this experience that one should not hesitate when thereÃ‚Â´s a chance to help someone -just do it. Your body knows what it is doing.
