7. You must hold your teacup properly.
Not only are you told how and when you can finish eating your dinner, but you’re told how to hold your teacup and there is a correct way to hold a cup apparently. You should pinch the top of the hands with your thumb and index finger; holding the handle at a specific angle and drinking from the exact same spot. So next time you see a picture of one of the royals (Kate in particular) holding a teacup, you’ll see she’ll be holding it in that exact way.
