The little sparrows and nightingale sing such lovely songs. They sing songs of laughter, happiness, and love. The big black birds do not sing songs such that. They more like preach about despair, sadness and death. I wonder what would happen if we switched the two. What would we think of the lovely little song birds that sing about despair, sadness and death? What would we think of the big black birds started to preach about laughter, happiness and love? I think I will just keep the them the same.
