Riding first class

I do not have much time for a long posting today. But I have arrived safely in New York. However, during my ventures I went on to a train and sat down. I was told that I was not allowed to sit there. I thought to myself, "I am not allowed to sit in a chair?"

But then I realized that they are commenting as to the color of my skin. I suppose that this freedom will have to be a step before freedom, for I guess that I am not really free at all, if I cannot even sit in a chair.
