I saw this photograph on the The Big Picture, and I was so moved by it that I thought I'd post it here as well (with its original caption copied beneath). 

President Obama bends over so the son of a White House staff member can pat his head during a family visit to the Oval Office May 8, 2009. The youngster wanted to see if the President's haircut felt like his own. (Official White House Photo by Pete Souza) 

Now I'm not totally ga-ga over Barack Obama, like many others.  I have genuine issues with some of his policies -- but I really respect him as a person (at least what I know of him).  And it's especially meaningful to see the way that his life offers significant hope for future generations of African-Americans.
