Girls are the only ones who can really give each other close attention, the kind we equate with being loved. They noticed what we want noticed.And that's what I did for Tamar, I responded to her symbols. To the style of her hair and clothes and the smell of her L'Air Du Temps perfume. Like this was data that mattered. Signs that reflected something of her inner self. I took her beauty personally.
