The character Joy in "Good Country People" is a great example of a physical representation of the burden everyone struggles with in the search to obtain "joy." For southerners, or people in general, being happy and finding joy in life is basically what everyone longs for. But so many are blinded to or unable to see how to acheive this because so many falsehoods are in the way. For example, the character Joy had a fake leg, maybe this could physically represent what all the falsehoods in the search for finding joy are like. Without the leg, Joy was unable to be stable, she couldnt walk and became physically incapable of going anywhere or moving forward. I dont really have an exact answer for what all this could mean, but i defintley think it means something. Maybe its showing how people are perfectly capable of obtaining joy, they just have to rid their lives of falsehoods. Or maybe it means that without these falsehoods we would be unstable, and unable to move forward because we've already gone as far as we could go.
