Rosa Parks is one of my heroes. Without intending it she sparked the rise of the Civil Rights movement--at least to white people's eyes. I once heard her (on a TV interview) say that she wasn't meaning to start this big hoopla, she was simply tired and didn't see why this white man should have claim to her seat so she just stayed there. She simply listened to that small voice that says "no" to injustice and refused to move.
This is really all any of us can do. We can only listen to the voice within us that tells us something isn't right and if we follow this voice we can do good things, small things that help to bring about some small victories of justice in this world. Rosa Parks showed us this truth. She was simply tired and refused to be bullied. It took great courage for her to do this and it took great strength even if she was tired.

God bless you, Rosa Parks!
