Twelve years after throwing me out, my mother appeared at my estate. She brought a moving truck with her. I knew exactly what to do.

One afternoon, while I was examining an old wooden cabinet, she gave me advice I never forgot.

“Never feel ashamed of a crack,” she said. “Just make sure you understand what caused it.”

At Grandma’s kitchen table, I could finish a sentence without being told I was creating problems.

I could talk without competing with Mallory.

I could simply be myself.

Before she died, Grandma Elaine secretly left me $900 inside an old cookbook.

It wasn’t a fortune.

But to me, it felt enormous.

It was the first thing I had ever owned that felt completely mine.

When she died during my final year of high school, whatever balance remained in our family disappeared.

Mallory stopped pretending to share.

My mother stopped pretending to treat us equally.

And then Mallory became pregnant.

She was nineteen too, but somehow the rules were different for her.

Grant moved into our rented duplex carrying two laundry baskets, an enormous television and no reliable source of income.

My mother immediately decided that my bedroom was the only room large enough for a crib.

I tried to reason with her.

I asked whether I could temporarily sleep on the living-room couch until community college began.

She shook her head.

“Grant has problems with his back. He may need the couch.”

“What about the basement?” I asked.

“We need the basement for the baby’s belongings.”

Then she crossed her arms.

Her next sentence divided my life into two parts.

“You’re nineteen, Paige. At some point, you need to stop being my responsibility.”

Mallory stood behind her, one hand resting protectively over her stomach.

“You’ve always acted like you don’t need anyone,” she added. “This shouldn’t be difficult for you.”
