Puppies for sale

A little boy was walking back home and he saw this advertisment board outside his neighbour's house. "CUTE LITTLE PUPPIES for sale, please contact 9670XXXX, price is negotiable." So the little boy knocked on his neighbour's door.

"Hi Mr Watson, I would like to buy one of your puppies!"
"Well, these puppies cost a good deal of money as they come from good parents." said Mr Watson.

The boy dropped his head with disappointment. The he reaching deep into his pocket, he took out a handful of spare change, and hand it to Mr Watson.
"I've got forty-cents, is that enough to take look?"

"Sure!" said Mr Watson. And with that, he let out a whistle. "Here Max!" he called. Out from the kennel and down the ramp ran Max and followed by 4 little balls of fur. The little boy pressed his face against the fence, with delight dancing in his eyes.

As the dogs made their way to the fence, the little boy noticed something stirring inside in the kennel. Slowly, another little ball of fur appeared, this one noticeably smaller. Down the ramp it slid. Then in some awkward manner, the little pup began hobbling, trying it's best to catch up with the others.

"I want that one!" the little boy exclaimed.
Mr Watson knelt down by the boy's side and said, "Son, you will never want that puppy. He will never be able to play and run with you like those other pups would." With that the little took a step back, and rolled up one leg of his trousers. In doing so, he revealed a steel brace running down both side of his legs, attaching itself to a specially made shoe.

Looking back at Mr Watson, he said "Sir, you see, I don't run too well myself, and he needs someone who understand." With tears in his eyes, Mr Watson reached down and picked up the little pup. Holding it carefully, and handed it to the little boy. "How much?" asked the little boy.

"No charge." answered Mr Watson. "There's no charge for love."
