I recently went apple picking with some friends and my Little Sister. It was an extremely eye-opening experience to go to an apple orchard with a little girl from the inner city.
She didn't know that apples grew on trees. When I told her, she looked at me like I was trying to pull a fast one on her. When she finally saw that I was serious, she asked me if any other fruit grew on trees. Each one was a whole new revelation for her. She told me that she had been sure that apples grew on the ground.
