It was just a blue, blank scrap. And yet still, somehow, he knew it was a library card. Problem was, he wasn't sure how it worked. He thought maybe it was like a ticket, giving the holder admittance, as to a basketball game. Finding no ticket-taker at the door, he entered, walked up three steps, turned a corner, and found himself faciing a counter with a lady behind it. When the lady look up and saw him coming, she smiled as if she knew him. Was he supposed to know her? He walked up to the counter and showed her the card. He felt silly showing a blank card. "You collecting tickents?" je said. She took the card. She looked at it, then into his eyes. The silly feeling vanished. "No." she said, "this is not to let you in. It's to let a book out."
