What are you smiling about?” she asked. He drew back a few inches, cupping her face with both hands. “How did you know I was smiling?” “I could feel it on my lips.” He brought a finger to those lips, tracing the outline, then running the edge of his fingernail along the plump skin. “You make me smile,” he whispered. “When you don’t make me want to scream, you make me smile.”-Sophie & Benedict
