Can you recall any memorable instances of some particular smell you had in past ? What was it ? |
|
Answer» When I was a child living in my village, the smell of wet soil after first rain was so tantalizing that I will never forget it all through my life. Then in a second incident, I was travelling by a local train from Borivali to Churchgate in Mumbai. Since I was not a regular resident of Mumbai, I was little worried about the station I had to get down. Some passengers in the train were just sleeping or dozing. Out of curiosity I asked one of the passengers, “How would you know if your station skipped without looking out of the window?” He laughed and told as a regular commuter, “We know which station the train is passing by,” More eagerly I asked, “How?” He told, “Smell of each station is different and we know by smell. If Bandra passes, the bad smell of sewage water is there; if Ville Parle passes, the smell of baking of biscuits is there and so on.” I was greatly surprised. |
