A funny interaction with a stranger

In my journey from home to my work place I take the local train. On Raksha Bhandan day, the train was unusually crowded. I had to stand in between the two seats facing each other in the train for most part of the journey. Since I did not get a place to sit I had placed my back pack on the top rack provided in the local train for luggage. When it was just 4 stations remaining for me to get down I happened to get a place to sit. There was a married couple seated face to face with each other. Both mother and dad carrying one of their kids on their lap. They had to get down at a station which was two stations prior to mine. I sat down next to the father of the kids. Due to the unusual rush, the father felt that it will be difficult for the couple to reach near the exit on time. Hence, he told his wife that they would need to make their move quickly so that they do not get stuck especially since they have their two kids to be carried as well. However, this conversation was overheard...
