Culture shock?what is culture shock?have we involve in culture shock?erm..yes,i admit that i had been involve in culture shock years ago but getting slow down.. but there are many types of culture shock. one of that is people start to changes physically or morally when they are in different places. instead i saw my friends involve in that issue. they easily influence by the environment and their best friends as well. most of my friends now are changes.they are too social in relationship.sometimes doing the bad thing.what happens to our world??where the value as a muslims??here, what i want to say is don't easily be influenced by other person especially in doing unethical or bad behavior. to my friends and to myself as well, i hope that they can changes and they must realizes that we lives in this world only for temporarily.. this world is belong to Allah s.w.t...
