My conscious awareness of the meaning of the word “stepparent” didn’t begin until I married a man with three adult children. For someone is not a stepparent unless they are legally married to a person who has offspring from a prior relationship. I really should have known this, or at least given it some serious thought, because my mother was the stepmother to my father’s daughter from his previous marriage, a girl who therefore legally also became my half-sister because we had the same father.
When I was a kid I would scour the landscape for mothers with children and watch them as though through a microscope. Mothers with packs of children followed us everywhere – to our dentist’s and doctor’s offices, to the gas station, the grocery store, the laundromat and the bank. They drove up behind us at the window at McIlhaney’s Dairy to exchange their glass milk bottles just like we did, the back seats of their Pontiacs and Chevys and Plymouths stuffed with bored and grim-faced kids who had been dragged along on these usually Saturday morning excursions just like my brother and sister and I had been. They would pull up next to us at an intersection, check us out, then speed off down the road leaving our car covered in silky New Mexico desert dust.
