Jenna McCarthy quotes:

What do women do when they get together? We sit around and talk! Men, not so much. My theory is that this difference is genetic and dates back to the hunter-gatherer societies, when the men had to be quiet as they hunted, lest they scare away the bison and then everyone starved to death and it was all their fault.

If you had asked me when I was 28 and in my wedding dress if I ever thought I would end up in my forties flipping my husband the bird over potato chips, I'd say you were crazy.

Now, as husbands go, I have to admit I did all right. Joe is unquestionably handsome, doesn't leave ragged toenail clippings scattered about the house, and has never once, in nearly five thousand days of togetherness, left the toilet seat up.

[Newlyweds,] these optimistic young bastards, promise to honor and cherish each other through hot flashes and mid-life crises and a cumulative 50-pound weight gain, until that far-off day when one of them is finally able to rest in peace. You know, because they can't hear the snoring anymore.

I don't care how handsome or fabulous or funny the groom is, or how sweet and accommodating the bride, or vice versa. Marriage is hard.

As relationships progress, the time you spend smooching diminishes. Where kissing was once an enjoyable entree unto itself, it becomes a mere appetizer couples hasten through on the way to the main course.

Divorce is contagious. That's right - when you have a close couple friend split up, it increases your chances of getting a divorce by 75 percent.

When you're pregnant, you go out and buy every single book; you have this stack of books on your nightstand, but there was nothing that was preparing me for anything even remotely resembling what my life was going to look like.

Scientific studies about relationships fascinate me, and I devour them hungrily, especially when they give big, fancy-sounding names to everyday experiences.

The man you married is yours to have and to hold for the rest of ever, even if he starts chewing tobacco or decides to pierce his hairy nipple and buy a Corvette, because you very plainly said - or at least implied - you were in it for better or for worse.

One study found that people who smile in childhood photographs are less likely to get a divorce.

Subsisting on a diet drawn from one food group isn't healthy or gratifying. Even eating cupcakes 24/7 eventually would get old!

Women, we care a great deal about being thin and good looking, whereas men mostly care about sex - ideally with women who are thinner and better looking than they are.

Women tell stories; men want answers. Guys get impatient when we drone on forever; we get frustrated when they tune out.

Merely watching a romantic comedy causes relationship satisfaction to plummet. Apparently, the bitter realization that maybe it could happen to us, but it obviously hasn't and it probably never will, makes our lives seem unbearably grim in comparison.

Beyond the profound federal perks, married people make more money; we're healthier, physically and emotionally; we produce happier, more stable and more successful kids; we have more sex than our supposedly swinging single friends; we even live longer.
