Most people behave differently when they are with different sexes, and there is also a difference between individual interviews and having a third person present. So as to get to know someone even better, and understand what they say better, you have to meet them in different places--even bump into them at different times on the same day.
大部分人在跟同性和異性相處時表現不同；單獨接受訪問與有第三者在場表現不同；在不同團體中表現不同；在初識和再度相見時表現不同… …，為了更清楚地認識一個人，以便真正聽懂他的話，必須在不同場合，甚至在一天中的不同時間跟他碰面。
