sentence: Curiosity is always silly or wrong.Some persons with nothing to do are  full  of curiosity about what their neighbours are doing.They are  anxious  to know what they are eating or drinking,what they are  bringing  home or taking outside,or  [MASK]  they have come home so early or late.To be interested in these things is  silly  because they are not at all  important  .It is none of their  business  to know what their neighbours do or are doing.Such curiosity is  something  not only foolish but also  harmful  .For most probably,it  leads  to a small talk which often brings harm,shame or disrespect to others,and thus  hurts  their feelings.
