Think about how often we fool people. "How are you?" "Oh I'm fine." You say with a fake smile.
I've heard many people, myself included, talk about the masks we wear. So many people, including those closest to us, don't even know we are wearing a mask. Sometimes we drop it and break it. That's when people see the real us. That is until we fix the mask, & magically everyone believes we are ok. Why do they believe that lie? Because they don't want to know the truth and we do a good job of making them believe it.
So to all my fellow actors & actresses I tip my hat to your abilities.
