““We begin to understand that to co-parent is to one day look up and notice that you are on a roller coaster with another human being. You are in the same car, strapped down side by side and you can never, ever get off. There will never be another moment in your lives when your hearts don't rise and fall together, when your stomach doesn't churn in tandem, when you stop seeing huge hills emerge in the distance and simultaneously grab the sides of the car and hold on tight. No one except for the one strapped down beside you will ever understand the particular thrills and terrors of your ride.””
