"You talk to them. And look at their faces. Cows have very expressive faces." I knew her well enough at that point not to be surprised by this. The first few months we'd worked together, I'd found her distant and intimidating, not just because she was Professor Preston's girlfriend, but also because she'd cultivated a very adult reserve that made her seem years older than the rest of us. She was all business at our editorial-board meetings, holding herself conspicuously aloof from the atmosphere of manic jocularity that dominated the proceedings. The more time we spent together, though, the more I'd come to realize that her reserve was rooted as much in shyness as in confidence, and that her quiet sophistication masked a powerful streak of girlish sincerity."
