Noted American scientist, George Washington Carver discovered three hundred uses for the common peanut.  Before embarking on his research he would open his bible and say,  "Mr. Creator, please tell me about this."  One day, he was walking to a university to deliver a speech.  As he walked a woman came out of her house and pointed to Carver and said,  "N****r, pack this wood into my house. "  Carver did then went on his way to the university.  As he stepped up to the podium to deliver he speech he saw that very woman sitting in the audience.  After he concluded his presentation that woman tried to apologize to Carver.  He replied,  "No need to apologize ma'am.  I'm always happy to do things for my friends."  That woman became Carver's friend for life and she supported the university until her death.  I don't know her name, or the name of the town or university.  I only remember the lesson and bring it out at times like these.  It always seems to help.
