It’s a basic fight or flight response to a stressful and potentially dangerous situation. Expats and local well-off HK people alike rushed to leave during the initial outbreak of SARS, for example. I did not live in HK then but saw the hordes of HK people arriving into my town in Canada, and remember reading articles about expats leaving with their families (not sure of the exact numbers but there certainly was some). SARS, much like the current situation in Japan, should not be taken lightly but also there was no need for utter panic and a desperate need to leave especially considering the virus spreads much easier on an airplane than if the people feeling would have just stayed put and thought rationally instead of letting emotions get the best of them. However, what did many people do? They panicked. Just like the expats feeling Japan. It’s during times of adversity when character is tested and it seems like the expats fleeing Japan have revealed their true character much like some of the expats and well-off HK people that fled HK during the early stages of SARS.
It’s all quite saddening and when/if the next potentially dangerous situation hits HK (whatever it is and whenever it is) I hope I have the strength to stay and help out the community instead of selfishly fleeing at the first opportunity.
