Bob Schieffer on the most important job: Mother I remember when my Mother died a friend said, "It takes a long time before you stop thinking of your Mother every day." My mother died decades ago, and I'm still waiting for that day. Somehow, some way, not a day passes that I don't think of her at least once - most days, four or five times. She was a child of the Depression who was widowed at an early age, but she devoted her life to seeing that her three children got what had been denied her: A college education. We all graduated - we were afraid not to! Yes, she loved us, but she was a tough customer who expected, demanded no less. Maybe that's why we made sure that all her grandchildren graduated, too. In the autumn of my life, I still hope she knows somehow when I do something that makes me proud. The other part is, I still worry that she'll find out about the things I'm not so proud of and come after me. In an election year, we talk about so many things that make a nation what it is and ought to be, but I believe the real core of our strength goes much deeper, and it's simple: It goes to the mothers who teach us what is right and wrong. All the rest of it grows out of that. So Happy Mother's Day, Moms. Yours is still the most important job of all.
