Ah, Weddedness!

 Asked what she had learned from 45 years of marriage, a close acquaintance of mine said:

"Never assume someone is dead just because they're unresponsive."

Which inspired me to a bit of would-be wit:

"Say what you want about marriage, it's still the best known cure for unnecessary conversation."

And then to a bit of actual wisdom:

"So often the person for whom you would climb any mountain and swim any sea would settle for a little conversation at dinner."
