NOW YOUR TURN! You will write a friendly letter to a relative. If you want a greater challenge, imagine that you are either a factory worker or a slave in the Civil War. Write a letter to your relative who is on the other side of the war. If you are a factory worker, write to your Confederate relative. If you are a slave, write to your Union relative. Include commas in all the right places. That means to use commas in the heading, greeting, body, and the closing.
