Passing through an unusual crowd in front of the metro station, I reached the entry gate, where two policemen were standing apart from the station security guard. One of the policemen asked me where I wanted to go. He said the trains on the route had been temporarily halted. I walked back home through a different route. On the way, I saw a phrase written on the board outside the wall of a shop - Building for Rent. I thought it was funny. Why did they want to inform the public they were building the shop for rent? I couldn't see any construction going on. The shop seemed recently vacated and repainted, which bewildered me. I realised the word building was used to refer to the shop structure. I assumed the word was used to refer to the construction. In other words, my mind expanded the phrase as "We are building it for rent" instead of "This building is for rent."
