Misunderstanding

In recent days, HSI falls a lot. Maybe I look depressed (but due to another reason), many colleagues and supervisors wrongly think that losing money makes me unhappy, for example：
范總：「點呀你，無晒心機咁，輸好多啊」
採訪主任：「點解塊臉黑晒」、「總之記住錢財身外物」
Although I have lost during this downturn, in fact stock will never affect my mood largely and for a long time.
