I am stating two events here which shows the difference of mental states of people in different part of the world.
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.
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.
