Barack speaks about his presidency, the future presidency and the way the United States made him better. He proves his points by backing it up with past events.
"Whether we have seen eye-to-eye or rarely agreed at all, my conversations with you, the American people — in living rooms and in schools; at farms and on factory floors; at diners and on distant military outposts — those conversations are what have kept me honest, and kept me inspired, and kept me going. And every day, I have learned from you. You made me a better president, and you made me a better man."
Traditionally a sonnet follows the subject of love EX: Italian Sonnet by James DeFord or Sonnet Number 18 by William Shakespeare
