Life in the Zuckerman barn is comfortable but quiet for Wilbur. The other animals — a horse, geese, sheep, and a crafty rat named Templeton — are not hostile, but they are occupied with their own concerns. Wilbur spends his days eating, sleeping, and waiting. The routine is dull, and he is lonely. One night, a voice speaks to him from the darkness of the barn. He cannot see who is speaking. The voice promises to be his friend and tells him to sleep and wait until morning. Wilbur searches thoroughly the next day but finds no one. It is only later, looking more carefully, that he spots the source: a small grey spider hanging near the top of the barn doorway. The spider's full name is Charlotte A. Cavatica. She is not large or striking in appearance, but she is highly intelligent, patient, and skilled. She is direct about her habits — including the fact that she eats insects — but she is also genuinely warm and steady in her loyalty. She has noticed Wilbur and decided, without being asked, to be his friend. For Wilbur, this changes everything. He is no longer facing the world alone. Charlotte has made a deliberate choice to look out for him, and that choice becomes the foundation of the story's most important relationship.
