`` i saw a man once that had a big purple one on the side of his face-one of those wagoneers that comes by to pick up the turnip crop in the fall - anyway , the mark was all over the side of his face , and i thought it was a big bruise at first and thought that he must have been in an awful fight - those wagoneers fight all the time - but then i saw that it was n't really a bruise but - like zubrette just said - it was a birthmark .
