Solomon Northup stated various contrasts in his autobiography, and one of those contrasts was that he spoke about politicians arguing about slavery in the capitol, when they had slaves right in their own backyard.
This use of contrasts can be useful in my autobiography, of course, without using his, but in my own way. I never really thought about using contrasts in my autobiography, I just thought about telling the story, but now, when I write down my own, I will have that in mind.
How can I adopt them? Well, I’m not sure right now, since I pretty much don’t know all the information I’ll put in my autobiography. Even so, I’m sure I’ll find out.
