NATICK — Kamala Harris recently shattered one proverbial glass ceiling, becoming the first woman — and woman of color — to be elected vice president of the United States. For Amanda Parker of Natick, the next glass ceiling that needs to be pierced is for a woman to become president. Parker, who works as a human resources professional at Newton-Wellesley Hospital, is sending a message to young girls that they can occupy the top in spot in American politics — or be anything they want to be. She's doing it through a board game that she helped develop called, “The Madam President Game.” “It turned into a lot more than we thought,” Parker said of what started as a brainstorming session with two friends from Maine — Stephanie Guidetti and Suzanne Hand.
