“Happy Stepfather’s Day!” said no one, ever. That’s an exaggeration—but not by much.

I haven’t been the world’s most grateful stepdaughter. Nor has my son been the most emotionally demonstrative stepson to my husband James.

That couldn’t be true. Weren’t stepmothers the ones who were ugly and homicidal in practically every Disney movie and Grimm’s fairy tale?
