The moon symbolizes many repeating elements in this play. They speak a lot about when the moon is out, time goes by quicker and it's the best time to go over your thoughts. Many characters have to make big decisions before the new moon.
"I wanna touch the earth, I wanna break it in my hands, I wanna grow something wild and unruly. I wanna be the only one for miles and miles, except for maybe you and your simple smile." (Dixie Chicks- Cowboy Take Me Away)
