While Mike's father babysat Boyd, he gave Boyd a small smack. This sets off a debate of parenting styles from different generations. Boyd learns to take advantage of his parents who do not spank, and Kristen feels she was spanked too much.
To spank or not to spank, that is Kristen's question. She and Ryan have sworn to never spank Boyd, but when he runs out in front of a moving car she does it. Guilt starts working on her and Ryan's condemnation isn't any better. Granted Mike and Vanessa think that her spanking him in that situation was just good parenting.—timshehan
