" The thing about Sam was that he had a tell. Well, two. They weren’t an exact science, but they gave you a sense. One was his hair. He had a great head of hair. Dark and longer on top, his ex-girlfriend—who came up as “Liar” on his phone now—had referred to it as irresponsible hair. If it was relaxed and tucked behind his ears, Sam was chill. If it was slicked back, he was spoiling for a fight. If it was fluffy—a very rare treat—it meant he completely trusted whoever was around at the time. Sam’s hair hadn’t been fluffy in a while. Today it was tucked back yet also, kinda, done. With the telltale sheen of product. It was inscrutable. "
