A visitor calls...

I heard a tapping at the window, and raised the blind to investigate. Standing on the small ledge outside my window was a delightful character, whose name was Cedric, wearing a scarf and a pillbox hat.

"Could I come in, please?" he said.
"No." I said.
"Please," he implored, shivering.
"No." I said.
"Please," he begged. "It's very cold out here."
"No." I said. "It's for your own good. It's very warm in here."
"Please..."
"Ok," I said. "Come in."

Cedric looked at me meltingly.
