The document is a story explaining why people get butterflies in their stomach when feeling nervous. It tells of a young girl named Sophie who swallowed a butterfly that laid magical eggs in her stomach. When the eggs hatched into caterpillars, she would feel them flutter around whenever she felt nervous. As she grew older, she realized this was why she had the strange feeling in her stomach when anxious. She eventually learned from a wise man that the magical butterfly story was true and this explained the butterfly sensation.
