A fostering-family-friend of ours called today to tell me a story. They have two new lap dogs, and one is the runt of the litter. After explaining to her daughter what being the runt of the litter meant, her daughter said, "Remember that runt that we used to take care of?"
Her mother asked about a different puppy, but that was not what she had in mind. She said, "No mom - he's a human runt. He lives with Teenager now. He's all grown up now. Not grown up like tall, but grown up on the inside, in his head."
Since a runt needs extra care and attention, she figured that Whistle must be a runt, too! :-) He lived with them for a month before he came to us, and we will be forever greatful for this mom's call when she said, "I think you need to meet this boy."
