It was that it became, it flourished, because I could say things to Stella that I wouldn’t have said to anyone back home—knowing they would only respond with bafflement, or laughter—and she always volleyed right back, sharpening me like a whetstone to a knife. I didn’t just want the friendship of this dazzling girl. I wanted the world that had made her so dazzling in the first place.”
