1. Rittenberg hooks the reader by stating that his dad was upset while talking to his mom about his future. Its something that would intrigue an 18 year old because we know exactly how he must have felt when he heard his dad get upset, especially about his future.
2/3. He talks about how his grandparents came through ellis island, and his dad served in the war. He also states that both his parents and grandparents had to go through two world wars and segregation. But then he goes on to say that they also saw those world wars end, same as segregation. This shows hope to the things we will see and have seen.
4. Tomorrow will be a better day was repeated over and over again through out the article. I think he just wanted to emphasize this specific statement and let the reader know it isn’t some sob story, it has hope to it.
