The theme of the monsters are due on maple street is it is easy to go into chaos. When they all go on to Goodman yard and they start talking on how he and his family are the monsters. And in Charlies words ODD BAY HE AND HIS FAMILY... Wichita shows how anyone can just jump to conclusions just because they are scared. When Goodman says that he has insomnia they don't belive him and even one of the women says that she sees him outside at night and looking at the stars like he was looking for something or waiting for something. He r enforces that over and over that he can't sleep well at night and that it is acused by him having insomnia for when they don't belive him he calls them scared rabies Wichita is accurate on how they scared and trying to find a scapegoat so they won't feel scared. Good man is actual trying to reason with the rest saying that he and his family are just like the normal and not anything supernatural. and at the end even the aleins reinforce it by saying how pathetic and how easy humans get up to their own necks.
