Obama wrote a piece for Parade magazine:
As the father of two young girls who have shown such poise, humor, and patience in the unconventional life into which they have been thrust, I mark this Father’s Day—our first in the White House—with a deep sense of gratitude. One of the greatest benefits of being President is that I now live right above the office. I see my girls off to school nearly every morning and have dinner with them nearly every night. It is a welcome change after so many years out on the campaign trail and commuting between Chicago and Capitol Hill.Obama's Father's Day event:
But I observe this Father’s Day not just as a father grateful to be present in my daughters’ lives but also as a son who grew up without a father in my own life. My father left my family when I was 2 years old, and I knew him mainly from the letters he wrote and the stories my family told. And while I was lucky to have two wonderful grandparents who poured everything they had into helping my mother raise my sister and me, I still felt the weight of his absence throughout my childhood.
As an adult, working as a community organizer and later as a legislator, I would often walk through the streets of Chicago’s South Side and see boys marked by that same absence—boys without supervision or direction or anyone to help them as they struggled to grow into men. I identified with their frustration and disengagement—with their sense of having been let down.
In many ways, I came to understand the importance of fatherhood through its absence—both in my life and in the lives of others. I came to understand that the hole a man leaves when he abandons his responsibility to his children is one that no government can fill. We can do everything possible to provide good jobs and good schools and safe streets for our kids, but it will never be enough to fully make up the difference.
That is why we need fathers to step up, to realize that their job does not end at conception; that what makes you a man is not the ability to have a child but the courage to raise one. Read the rest here.
