I know why the caged bird sings, ah me, When his wing is bruised and his bosom sore,- When he beats his bars and would be free; It is not a carol of joy or glee, But a prayer that he sends from his heart's deep core, But a plea, that upward to Heaven he flings- I know why the caged bird sings!
Paul Laurence Dunbar (2012). “Selected Poems”, p.28, Courier Corporation
