If there is a sound downstairs during the night and it might be a burglar, you don’t say to her, "This is an egalitarian marriage, so it's your turn to go check it out. I went last time." And I mean that–even if your wife has a black belt in karate. After you’ve tried to deter him, she may finish off the burglar with one good kick to the solar plexus. But you’d better be unconscious on the floor, or you’re no man.
- John Piper, This Momentary Marriage
