Teddy came thundering down the stairs, much to his father's annoyance. "Teddy," he called, "how many more times have I got to tell you to come downstairs quietly? Now, go back upstairs and come down like a civilized human being."

There was a silence, and Teddy reappeared in the front room.  "That's better," said his father, "now in future will you always come down stairs like that."

"Suits me," said Teddy. "I slid down the railing."
