I didn't even need to ask -_-;; Mum use to tell me how much she made and how much she was spending to pay bills and food, and later on dad did the same thing. And when I told them that a lots of Australians didn't know how much their parents earned, my parents gave me this blank look. They just assumed all parents told their children how much they earned and how much they needed to pay for bills, so to teach them how to budget and stuff.

Mind you, I'm from Main-land China, I have no idea if the South East Asian Parents tell their children or not.
