Like the saying goes if you don't have anything nice to say it is best to say nothing at all. When you are angry your words come out spewing anger on anyone within earshot. Even if you don't utter a word your face shows it. And your mom was right when she said don't make ugly faces before it sticks on you forever. And those deep wrinkles you make when you are mad don't go away. The next time you get angry look in the mirror and you will know why you need to flush.
