【Life is also like riding a train. The scenery in the past is so beautiful that you linger and are reluctant to leave. Yet, you always need to move forward; you will have to depart. You tell yourself, "It's okay, I will surely come back to see it again in the future." But in reality, you will often never return. Time that flows away, scenery that recedes, and people you encounter along the way will ultimately drift apart.】
