"Doesn't matter. What's wrong?"
"A lot of things," I looked at him, smiling halfheartedly. I paused. "Do you think there's a difference between being sad and lacking happiness?"
He nodded, and I nodded back, glad that he understood. Neither of us said anything else, but I felt a traitorous silent tear slide down my cheek. He put his arm around my shoulders, and for once, I had a shoulder to cry on.
