Chapter Five:
A Visit from the Wicked Witch of the Deep South
"My, the river's flowing fast. I'm glad it's not that deep," said the Tin Woodman, after they were underway. “If it were, and I fell overboard, I could rust up solid for all eternity. Do you think the raft will stay big? Oh dear, what if it gets little again? We'll all be spilled into the water!"
"Don't worry so much," said Dorothy, smiling. "You'll worry yourself to death."
"Can people really do that?" asked the Tin Woodman. "Worry themselves to death?"
"Of course not," laughed the girl. "But I suppose a person could become quite sick if he constantly worried over things."
"Never worry worry, 'til worry worries you," said the Scarecrow in a matter-of- fact tone.
"What is that supposed to mean?" inquired the Tin Woodman.
"I think it means," answered the Scarecrow, "don't worry about something until it actually happens."
"Oh! I see," said the Tin Woodman. "In other words, most of our worries never materialize, so why fret constantly over something that in all probability will never occur?"
