My mother is visiting this week. Last night, after putting my son to bed, I lowered my pregnant self onto the sofa and revved up the DVR. Mom said she didn't care what we watched. So I clicked on the newest episode of AMC's "The Walking Dead." As the credits rolled, she stared at me in horror. "This is your favorite show? Isn't it about, like, zombies? How could you possibly relate to or enjoy a show about zombies?" Quite easily, in fact.
