Passanger with luggage on his head

A typical indian train was going along. All passangers were well seated. Among them was a man who was holding his bag on his. I suggested to him that there is enough space around and so he could keep his bag down. He refused by wave of his hand. Being an Indian I could not keep off my curiosity. I prodded further. I asked why he was holding his bag on his head. He replied, "If I dont take care of my baggage, who would?"!
