Two single adults become caregivers to an orphaned girl when their mutual best friends die in an accident.

Eric Messer: Having somebody help you doesn't mean that you fail, it just means that you're not in it alone.
Sam: If my wife and I fought like that... we'd still be married.
Holly Berenson: They love Sophie more than anything in they entire world, and out of everyone, Messer, they picked us.
Eric Messer: Just because you accept help from someone, doesn't mean you have failed. It just means you're not in it alone.
Simon: You know what marriage is like? Imagine a prison, and they don't change anything.
Eric Messer: I never had to think for three people before, hell, I barely had to think for one.
Eric Messer: So I'm at the drug store and it dawns on me that women stare at men carrying a baby like a guy will stare at a woman with a great rack.
Eric Messer: If me at any age of my life could see me right now he would kick my cat ass, you know that?
