I am finding this distressingly easy to imagine.
Odd that this should come up, what with the wife out of town even as we speak, with the kids to boot!
Let’s see. . . .
I came home and walked the dogs. something I never do because the kids take care of it.
Then I ordered pizza. After it arrived I stripped to my undies and watched TV all night. I also consumed copius amounts of beer.
Too bad she’s only gone for a couple of days.
My hubby is gone every week so this is more like “Things I Don’t Do When Hubby is Home”
I detox.
I clean the house once and it stays clean.
I go to movies alone and see esoteric movies (Monsoon Wedding last night!) if the nanny is around.
I take the kid to paint your own pottery places.
Kiddo sleeps in our bed with me.
I exercise.
My hubby goes away pretty frequently these days. His latest job takes him out of the country for a week or more every month.
Since we have 4 children, my day-to-day life doesn’t change that much, except that I become responsible for things that he would normally do, like dropping our oldest off at school every morning and taking the trash to the dump.
I do take some pleasure in draping myself over as much of our king-sized bed as I can reach. And I eat salad for dinner every night.
It’s interesting that so many people say they drink less. My husband doesn’t drink and I find myself drinking more when he’s gone because when he’s around I usually feel sorta self-conscious about it.
I just generally enjoy the “feel” of the day. I can get up knowing I can do whatever I want without discussing it w/ anyone–it doesn’t matter what. Just knowing the options are WIDE open feels great. I can see stuff on tv he would criticize me for otherwise. I can get bummed about having to clean up my own mess vs. pissed about cleaning his! There is just something about the solitude that re -charges my battery.
I find it interesting how many people would do stuff that I do anyway. I’ve never spent a night apart from my husband in the eight years we’ve been married, but I guess if I had to, I would rent some movies that he wouldn’t be interested in (read: chick flicks), hog the bed and otherwise do nothing differently. I’d still play computer games or lay on the bed and read. I might order pizza, but his being here or not wouldn’t change that. I wouldn’t drink, because a) I don’t drink anyway and b) the rare times I do, it’s always with him.
Just wanted to say that this is the same for me. My fiancée does drink, but very rarely and has very strong opinions on it. Part of it may be that he’s older than me, or perhaps because his friends are very straight-laced and therefore bad influences. 
It’s a bit of a culture shock for me as I come from a family of happy go lucky lushes. They are that loud, big group of people at restaurants, the type that talks big, eats big, drinks much and loves life. shrugs
Whenever he goes away I tend to whip up a homemade pasta dish… pasta primavera or fettuccine alfredo usually. I then watch a movie and happily sip my red wine. I also love buying strawberries and grapes for my ‘fiancée away’ nights. It feels so decadent to light candles, read a good book, sip wine and savor fresh fruit.
