Casual Discussion on Common Practice of Society 

Casual Discussion, from my understanding, means both casual and extensive. However, the common practice of society is not suitable to be said casually or too much because of its great difference in different people. Therefore, my discussion on common practice of society, in fact, is of a little "difficult to say" taste. This "difficult" has three meanings: first, it»s not good to say it reluctantly; second, it»s not necessary to say it but have to say it; third, it»s inconvenient to say it but have to say it.
