Stabler and Benson in “Unfinished Business”

Stabler

[about his marital troubles] It never goes away, y'know? Each case a little more horrific than the last. I go home, what am I supposed to do, talk about my day at work? "Honey, today a guy cut a baby out of his wife's stomach. Pass the gravy, please."

Benson

So you just don't talk at all? That's no solution, Elliot.

Stabler

One of us has to be able to sleep at night. She thinks I'm shutting her out.

Benson

You are. That's exactly what you do. You keep this up, you're gonna ruin the best thing you've ever had.
