I picked this answer because in the expert he uses Black English to explain how this white man or white people in general may not understand the struggles of being a black person back in the day and in the present. Plus using the Black English is a great thing to use in this expert because it helps the man connect with him and understand where the black man is coming from, if that makes sense. Hopefully this helps!
Many things can be learned from a journey. You can learn from your mistakes and learn to not make the same mistakes. You can also learn alot of things about yourself, depending on what the journey is.
