I'm sitting at my computer but I see our big black labradoodle, Moo (imagine calling for her on the street), curled up for a nap in an armchair. I look at her with love but also with more than a touch of envy. Because as much as the stacks of papers on my desk beckon (or is it taunts) me, a nap's what I really want, and probably need.

The reasons why are unimportant but probably familiar to most people. I stayed up later than I planned, then my sleep was interrupted during the night by Moo, a crazy morning filled with unplanned things that delayed what I'd hoped to have accomplished, which meant I was now working at full speed to "catch up" and I felt exhausted. Not to mention, this morning's caffeine had worn off hours ago.

You may be thinking, "You work from home, just stop what you're doing and take a nap." Well, it sounds like good advice except I'd feel guilty doing that, especially during a workday. A nap just seems selfish. Plus, I'm not sure how I'd explain it to Black, although she doesn't sleep normal hours, and does take power naps.

Anyway, a few days later, my eldest daughter sends both my sister and me a photo of her cat, Porsche (yes, like the car), fast asleep in her bed. And while I was busy typing something warm and fuzzy in reply, I saw that Black had already responded,

Some things never change … like a love of naps.

That made me smile, as it was so true of both Natasha (and all college students?) and her cat, and when I mentioned that to Black later that night, she explained that cats are notorious for sleeping up 16 hours a day because they're saving up their energy (remember they're hunters in the wild). Then she reminded me of how our Grandma Betty used to climb onto our kitchen table (no, I'm not kidding) and would take a catnap for 15 minutes. Then she'd jump up from the table, well-rested and ready to take on the world.

Black laughed that she must have inherited that trait (minus the kitchen table part) because she's taken power naps for as long as she can remember. In fact, she'd often take one in her racecar when waiting to go out on track, but even in her corporate days would close her door and take a 10-15 minute afternoon power nap. (She also couldn't resist sending me a Wall Street Journal, You're Going Back to the Office. What Happens to Your Nap Habit?, wishing that management realized the "benefits" of employee naps.) Anyway, the more we talked, the more I realized that naps can be incredibly beneficial, giving your mind and body time to recharge and recover.

All I know is that thanks to a dog, a cat, an unforgettable memory of my grandma, and basically "permission" from my sister, I think that the next time I need a nap, I might actually try to take one. And whether you call it a catnap or a power nap, I figure If it's good enough for Black, it's good enough for me. Maybe you too? (Although someplace you can close a door might be in order …)
