Dave said, "Why are you thankful for your dad?"
Without hesitation, Christopher answered,
"Because he sleeps in so I can do fun things with my mom."
Later on, Tanya (Christopher's mom) provided some context for his answer. Just that morning she had taken the time to tell each of her kids why she was thankful for them. When she got to Christopher, she told him she was thankful that he got up early with her so they could spend time together in the mornings while everyone else was still sleeping.
With that, Christopher's answer made perfect sense.
