In the intervening years Georgie had wondered many times if you could just keep making things faster by adding "per second" to the end. "Just how fast", he would wonder to himself as he scrubbed the toilet bowl, "would nine point eight metres per second per second PER SECOND be." Georgie tried to solve this riddle by himself, but he was not terribly bright. Sadly, by the time he had found a good way of phrasing the question, the young master had long since become an adult and moved to America.
One day Georgie found himself back on the twenty-fourth story of the Manor Manor hotel and couldn't help but remember when the young master had kept him from jumping. As he was scrubbing the toilet that day the "per second" question troubled him more than it ever had before. Before he knew it he was repeating "per second per second per second per second" over and over again under his breath and he was scrubbing so hard that the bristles began to fall out of the brush.
It was time, he decided to settle the question once and for all. Leaving the brush lying haphazardly in the toilet, Georgie marched into the library and for the first time in his life addressed the old master without being spoken to first. "Sir," he said, "I have something very important to ask you."
Surprised, the old master looked up from his book and removed his pipe from his teeth. "Yes Georgie," he asked kindly but with some slight impatience in his voice, "what is it?"
"How much faster, sir," Georgie began tremblingly, amazed at his own gall and filled with trepidation and excitement at the idea that he would soon have the answer, "is nine point eight metres per second per second per second than nine point eight metres per second per second?"
The old master narrowed his eyes slightly and then gave a very tiny shake of his head. "Those are accelerations Georgie, not velocities," he said as he placed the pipe back in his teeth and returned to his book, "for all you know the speed is zero."
Cowed, Georgie retreated from the room.
"For all you know Georgie," he said to himself as he opened the twenty-fourth story window, "the speed is zero."
