Jared opened the door to his house and entered a maelstrom. His youngest brother was screaming at his mother in the next room. He couldn't hea the details, but apparently she was mad at him for not picking up his things.
After he got in, he saw why: Mitch had apparently left his coat on the floor rather than hanging it up. No wonder she was upset. Still, given how stubborn they both were, this fight would probably go on forever. He decided to be helpful, and grabbed the coat of the floor, intending to hang it up.
