John Hatch wrote a nice rememberance of the history surrounding Rosa Parks and her famous bus ride. Included in his post was this detail I didn't know. "We often remember the story that Rosa was just asked to move to the back so a white man could sit in the front since there were no seats. Actually, there were seats, but Montgomery's segregation law made it so whites didn't even need to sit next to blacks; in other words, Rosa was asked to move so a white man didn't have to sit next to her, not just so he could have a seat."
I am so grateful for people throughout the ages who have been willing to sacrifice their own comfort to make the world a better place for everyone else.
