Confession - I've always said that when I "retire", I aspire to be an actor. I want to be one of those crazy old lady actors in movies and commercials. It wouldn't just be on-screen antics either. Every single day, I aspire to go all out. Think Zelda Kaplan (RIP) & Iris Apfel, Betty White & Cloris Leachman.
