I am stating two events here which shows the difference of mental states of people in different part of the world.
First Event
Place: London
One of my friend's friend started living in a peaceful colony in London. On the very first day he was trying to cook rice in his pressure cooker (which obviously had a whistle). When the whistle went off one of the neighbour, who had no experience with such pressure cooker, called the cops and informed for some terrorist activity. Police came like a bomb defusing squad they seized the cooker and took it for inspection. They returned it two days later but advised not to use it.
Second Event
Place: Bangalore
During one of the cricket match there was a news of a bomb-blast near entry gate. Fortunately no one got hurt in that blast. When my friend came back after the match, I asked about the blast. He said that he was sitting just near to the entrance gate and her heard the blast but he thought it was a someone celebrating with fire-crackers.
There can be many conclusion taken from these two real events but what I understood is that the people who live in a safe place get panicked easily.
