The Fool is represented by the Scarecrow from the Wizard of Oz. The Scarecrow's deepest desire was to have a brain; he didn't realize that his actual problem was ignorance. His subsequent adventures with Dorothy teach him that reality is full of joy and perils. He lacked education, but not insight. He might leap into the fire, but he'll learn from his mistake. Here in the South, 'sweetheart' is meant not as a romantic term, but as a description of someone who is kind and thoughtful. This lass appears to be communicating with a plant; every living thing deserves respect in her eyes. I'm sure she would willingly nurture the Fool and patiently teach him (while replacing his singed hay with fresh stuffing). People who are childlike can be frustrating when they act impulsively, but they can also teach us how to embrace each moment.
He is no fool who gives what he cannot keep to gain what he cannot lose. ~ Jim Elliot
