My wife and I have very different body clocks. At sundown she is practically ready for bed. I, meanwhile, am a night owl.

Recently, after a long, hard workday, I announced around 8 p.m. that I was exhausted and ready to hit the sack. Suddenly my wife nearly leapt into my arms.

"Oh, honey," she purred into my ear, "I just love it when you talk early to me."
