I lifted my sister off the ground as we embraced, and we laughed and laughed as we looked at each other. I picked up her bag and we began to walk to the parking garage, and she slipped her arm through mine. And I knew at that moment, somehow, that I loved her, so naturally, so easily and fiercely, that later, after she was gone, I would find myself mistrusting that love, trying to explain it to myself. Even now I can’t explain it; I only know that the love was true, and still is, and I’m grateful for it.
