This happened to me when I was 7 years old. I was traveling with my parents by train.
With lot of hustle bustle, we left home in a hurry to catch the train. We got into the taxi and sped to the station.
Since my sister was 4 years older than me, she managed to run quickly, but I was left behind. I could see my family running without me.
Since I couldn’t see them, I wondered which compartment or bogie was ours. Not finding my parents, I started to cry. Many people gathered around me asking, whose child is this? Then suddenly I heard a familiar voice. It was my dad shouting my name.
Seeing me, he grabbed hold of me and hugged me tightly with a sigh of relief. Since then, my parents make sure I am always with them while traveling.
