Might be a one time survey, i am thinking.... (so be it.)
Yet, i am wrong!
Today someone called again, and the anxious parents, knowing it was a call from Government sector, panicked. With their limited English words, they asked the person to call later, when i get home from work.
Indeed, a guy called. At 9:30pm.
First thing i asked him : "So late you all still working ah??"
Anyway from the about 15 minutes phone conversation
To minimize the parents from being panicked, i requested the next month to call to my mobile phone.
Every month same questions.
Why made my parents panick.
