Before Mama and Daddy were born but when all of my grandparents were born, there were rules that people with dark skin were not allowed to do all the things that people with light skin could do. I know that this was very wrong.
I learned that there were four students (but older students, not little kids like me) who went to sit at a lunch counter table that they were not supposed to use because of the bad and mean rules about skin color. Doing this started to help the ending of those bad rules.
