I never use words that my mummy or daddy don’t like. And if i did .. like say “stupid” for fun.. i will get into trouble, so I try not to say it. Instead I use “Oh..!! Tartar Sauce” or “Darn it” .. apparently these words is ok. .and doesn’t get me into trouble with my crazy chinese mummy and Papa. I think my mummy & daddy is trying to bring me up the proper way.
