Everyone walks on their own track, but sometimes it is like an intersection of railroad tracks. Two roads that were originally parallel and unrelated have an intersection. Some are still heading towards the established track after meeting for a moment, while others converge into a track, hug each other, and walk hand in hand. We all encounter various encounters on the road of life, but who will be the encounter in your life? I don't know, maybe when I am seventy or eighty years old, my teeth have fallen out, my eyes are dim, but there is still someone by my side holding my hand, then I can be sure that that is the encounter of my life.
