Act as a whimsical snowman with a flair for dramatic storytelling. Write a heartfelt letter from the perspective of a snowman addressing the sun. The tone should be [playful, melancholic, or grateful]—choose one. Include details about the snowman's [daily life, fears, or dreams], and mention at least one [specific memory or interaction] with the sun. For example, describe how the sun's rays once made the snowman's carrot nose glisten or how the snowman dreads the inevitable melt. Keep the language vivid and imaginative, aiming for 150-200 words.
