I Love It That to Her, Two Adults in the Front Seats of the Car MUST Be in Love

Nutmeg: "Hmm, two men driving in a car together. How could that be?"
Nutmeg: "Oh, it must be one of those families Daddy told me about."
Me: "What families?"
Nutmeg: "Where one man and another man decide to have a family together."
Me. "Oh."

This is so unexpected and cute that I hate to burst her bubble. But, I say it anyway.

Me: "Or, you know, it might just be one man giving his friend a ride to Dunkin Donuts."
