What are the motifs in Mule Bone by Zora Neale Hurston?

In a play that focuses on romance, sexuality would be expected to be a motivating force for a character's actions and words. Teets and Bootsie are former girlfriends of Jim and Dave, and both young men are now intent on pursuing Daisy. These serial relationships, though intermingled, appear devoid of sexual tension. Teets and Bootsie have gone on to other young men. There is much gossip about which young man Daisy will ultimately choose, but there is no question about possible impropriety.
