Excerpt 1. I think Walt Whitman is saying he is his own person and not phony, but he acts according to the type of crowd he's around. I found this excerpt interesting because sometimes you have to act accordling to the people your hanging out.

Excerpt 2. I think he means it really doesn't matter how poor or different a person is, you should still treat a person the same way you would want to be treated.

Excerpt 3. I choose this piece of work by Walt Whitman because in this writings he is talking about the death of President Abraham Lincoln.He really admired him and his doing.
