Steve is a minor character in Up.
Steve is a construction worker, working with the person who drove the truck that collided with his mail box. After the truck collided with the mail box, Carl was very annoyed, and even more when Steve wanted to fix the mail box, whilst he wanted to. To stop him from trying to move it, he, without knowing it would hurt him, hits his head with his walking stick. Everyone stopped, including the cars, and almost everyone came, to Steve. Carl was shocked, and hid in his house. When he reached the house, he peeked out of the window, and noticed the boss of the construction site looking at him. Carl soon had to go to court, and was there after deemed "public menace." This incident was used to make pressure on Carl and make him leave his house.
