Read the following excerpt from "Woman Who Helped Hide Anne Frank Dies at 100" by Teri Schultz. Ms. MIEP GIES: I, myself, I'm just a very common person. I simply had no choice. I could foresee many, many sleepless nights and a life filled with regret if I would have refused to help the Franks. And this was not the kind of life I was looking for at all.
SCHULTZ: Gies explained another motivation for emphasizing her modesty. She said if people are allowed to think it takes remarkable qualities to act boldly on behalf of others, few will attempt it.
Ms. GIES: People should never think that you have to be a very special person to help those who need you.
