Picture it—it’s Thursday night and you’ve had a long day of kids climbing on you, climbing on furniture, climbing on each other. You’re exhausted. You should probably go to bed, but you don’t—because moms stay up late. Or at least, they have a tendency to.

It’s our “me time.” No kids, no chores, no obligations to anyone other than ourselves and season five of Selling Sunset.
