Life is a capricious ride that never ceases to change. The increased flow of cultures in ASEAN region is just a part of it. A challenging lifestyle and communication are what I believe to be brought by these diverse cultures in the land of harmonized difference, ASEAN.
An alienated lifestyle is the most prominent change. “Culture shock”, the divergent turn of culture, might be an appropriate term for this; nonetheless, I would refer to this as ‘culture challenge’. The situation here is different from culture shock seeing that not only will you find culture variety in other countries, but you will find this in your own country. A once old picture of lifestyle, such as riding a bus with controversial people on it, will be replaced by a wholly new one, so new that it is not different from starting a novel life in an isolated land, like sitting next to a person of a different religion on the same bus. Days after that, the diversity of culture will just be a common story, just like the story of the man who cried wolf.
One component of human beings is, definitely, communication since we tend to turn our faces towards the society and away from isolation. The way which communication is carried out is through languages, a part of almost every culture and these unfamiliar languages are the second change expected. In the market, you might be able to find a seller using his native language interchangeably with the foreign language from which his customer comes. Ultimately, the communication obstacles will be gradually overcome and finally diminish.
In short, the changes of lives among the diverse ASEAN culture, from my view, are more challenging lifestyle, as well as communication.
