Setting the rules
After all, if John could not trust Katie with watching over his dog, then how could he trust her with children in the future? He told Katie that he was going to give her a list of rules to follow so that Charlie would be okay. If anyone knew how he was during the day, it was John.
But as John was going over the list of rules for Katie, he didn’t realize that she just was not listening at all. She thought that no matter what would happen, Charlie would be fine, in her mind, he was just a dog and didn’t need all of this special attention.
