I am thankful that I got to play Lady MacBeth in Dinner Theatre last year. I know it seems weird, but I learned a very important truth while I had that role. Lady MacBeth has a line that says, "What's done cannot be undone." I feel like I used to worry so much over the past and what I had done wrong and what I could have done. But after being Lady MacBeth I realized that what you have done, is done. You don't get that back. But you can always move on and make today better.
So basically I am thankful that Mama Loureiro cast me as the psycho chick. :)
