In the last two chapters of the book Their Eyes Were Watching God, an important theme that was depicted was: even when times get tough, you must to move forward with your life. 

In chapter 19, after Tea Cake gets sick, loses his mind, and attacks Janie; she was forced to kill him. Directly after she puts Tea Cake down the narrator says, "So that same day Janie's great sorrow she was in jail. And when the doctor told the sheriff and the judge how it was, they all said she must be tried that same day"(185). In this passage it is expressed that Janie never even got a single moment to grieve, before she had to progress through that day without a moment to pause. Even after murdering her husband(who she loved dearly) with her own bare hands, she must spend 3 hours in jail and face a room full of people and explain every detail of what happened. This shows that even when Janie has had the worst experience of her life at that time, she still went on with her life and did what she had to.

After shooting her husband to death and found not guilty in court, Janie must attend Tea Cakes funeral, "She went on in her overalls. She was too busy feeling grief to dress like grief"(189). Hurston uses the personification of grief to express that even though Janie was feeling a great amount of grief, she did not stop her life to grieve the death of her husband. She did what she knew was right, and attended his funeral. Even though she did not dress as nicely as she had for her ex-husband Joe's funeral, she felt more guilt towards Tea Cakes death. This lead her to have just enough will power to attend the funeral but not enough to "dress like grief" or to dress extravigantly, she simply wore overalls. The fact that Janie had had to murder the one person she loved most in the world, and then forced herself to attend his funeral afterwards, expresses the theme that even when times get tought, you must move forward with your life. 

Plot diagram:

A young man named Steve had come home from a long and stressful day of work. He had been fired from his well-paying job that day, had gotten dumped by his girl friend of two years and to top it all off, he had gotten a flat tire on his way home that afternoon. Steve was having the worst day of his life.  When he got home from this awful day all he wanted to do was collapse on his couch and enjoy a nice night of undisturbed sleep. Unfortunately he remembered he promised his 8 year old niece that he would take her out for ice cream for her birthday. This was the last thing Steve felt like doing at a time like this. So after a few minutes of self-pitying, Steve decided that just because he had a terrible day does not mean his niece must have one too. So he raced out to his car and sped over to his sister's house to take little Anna out for ice cream. After an enjoyable night of giggling, storytelling, and lots of ice cream, Steve drove home with a smile on his face and not a worry about the bad day he had, on his mind.
