Life is compared to a train journey with ups and downs. We board the train at birth with our parents but they cannot stay for the whole ride. We meet other passengers like siblings and friends who become important. Some have easy rides while others face difficulties. Passengers get on and off, some leaving lasting impressions while others depart quickly. We cannot control what others do but should make the best of our own journey. We should help others who are struggling and remember that any passenger's ride could end unexpectedly. When our own ride ends, there will be sadness to leave others but joy to eventually reunite at the final destination.
