Theme: Don't jump to conclusions because it can lead to destruction.
Evidence 1: "It's always that way, in every story I ever read about a ship landing from outer space."
What a weirdo', am I right or am I right?
Evidence 2: "... Mr. Goodman here in the wee hours of the morning..." "As if he were looking for something."
I have insomnia, ok?!
Evidence 3: "Steve-you know why I shot! How was I supposed to know he wasn't a monster or something?"
I didn't know it was somebody we knew!
One major theme of "The Monsters Are Due on Maple Street" is don't jump to conclusions because it can lead to destruction. Evidence 1 shows how Tommy jumps to conclusions and thinks that the problem is caused by aliens just because "it's always that way, in every story" he's ever read. In saying this, he made his neighbors feel scared and worried. My 2nd piece of evidence also aids my theme because it shows how Woman One jumps to conclusions and thinks that Mr. Goodman is the "alien". After saying this, he confesses that he has insomnia, proving to Woman One that she's wrong and "destroying" their relationship. Lastly, my evidence 3 supports this theme because it shows when Charlie jumps to conclusions. He thinks that the shadow slowly walking towards them is a monster, when really it is Pete Van Horn. Instead of waiting to see who the shadow is and what it's doing there, Charlie shoots and kills the "monster", not realizing it's Pete until they check the body. He soon tells them all that he was simply "tryin' to... tryin' to protect" his home. Later on, while everyone attacks him, he jumps to conclusions yet again and says that's it's Tommy who's the monster, causing another mob that destroys people's houses, relationships, and reputations. Those are the evidence and reasons to support the theme don't jump to conclusions is one of the major themes in "The Monsters Are Due on Maple Street".
