Mara had never understood why people were surprised that she had so few friends. At forty-eight, she could count her genuinely close relationships on one hand. She did not dislike people, and she was perfectly capable of being pleasant at dinners, work events, and family gatherings. But after years of forcing herself into conversations that felt empty, she had stopped pretending. Small talk exhausted her. Gossip made her uncomfortable. She preferred an evening alone with a book to spending hours discussing people who were not in the room.

Her daughter sometimes worried that Mara was becoming isolated. Mara insisted she was simply selective. She had learned that one honest conversation could mean more than a hundred casual interactions. Still, one evening, while cleaning an old box of photographs, she discovered a picture of herself surrounded by friends she had once trusted completely. She stared at the smiling faces and remembered how different she had been. Then she found a note tucked behind the photograph—and suddenly understood why her circle had become so small.
