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 will come and go, leaving impressions. Our companions may sit elsewhere or get off the train, but we can seek them out. Our final stop is unknown, as is when we will depart from our traveling partners. The goal is to make the most of the ride and help others along the way until we each reach our end station.
