As Emily says in act 3 of the play,
Oh, earth, you're too wonderful for anybody to realize you. (Wilder 108)
In dying, Emily realizes just how blind the human race is. Her heart is broken when this occurs.
where else can this theme be found?
This theme can be found elsewhere, as in the beloved Disney Pixar movie, 'Toy Story 2'. In it, the cowboy Woody gets stolen by a toy collector and is destined to be displayed in a museum in Tokyo. He is faced with the difficult decision of going home and risk being thrown away anyway, or to be immortal forever in a glass case. In the end, Woody, learns to appreciate what he has and to enjoy being played with while he has a chance.
What does this mean to me?
Personally, I believe that this theme tells us all to take a moment to relax regardless of how busy we are, and to use that time to appreciate our families and the world around us. Our days here are numbered. We should live our lives to the fullest today because tomorrow isn't guaranteed. So, go start treating life the way it should be treated!
