My short summary:

Tom was addicted to his work all of his life and neglected his wife because of it. he lost his yellow sheet of paper because it blew out of the window. he thought it was necessary to go retrieve the piece of paper, so he climbed a building and risked his life. He was hanging on the building scared for life. He had to smash a window to get back into the house. the experience made him realize that his wife was more important. so he went to find her and he only weighed the piece of paper down with a pencil and it blew away again.
