Billy glanced toward the door. He should make some excuse to leave. Or refuse to have a conversation. And he was about to get up and leave. To say he didn't really follow that sort of thing. But then what Mark said, it cut deep. People didn't think he was real? Was this true? Or was it just this guy's crazy theory? Did he know? Why else would he start talking to a total stranger like this?

"I really don't know about that," he said a strained smile. When he usually went out with his manager, he often spoke as little as possible. And when he did, he tried to mask his accent. But now, he didn't even attempt it. "Is this...is this how you greet everyone you meet?" He seemed cautious, holding himself back.
