"What are you doing?" Sam asked, eyebrows raised and an etch of frustration in her voice. "Doing what?" Kate looked at her confusingly. "Well, whatever it is you're doing? I thought you like me?" Sam almost sounds impatient, totally contrasting her soft, almost angelic face. "Yeah...? I do. So what?" "So why do you act like you don't?!" It was like Sam blew up but kept her cool not to get the librarian's attention. What does she mean? Kate doesn't know. She could only stare at the irritated Sam.
