“If you can’t keep up anymore, stop making everyone else wait.”

The woman behind us said it loudly enough for half the checkout line to hear.

My mother, Dorothy, was eighty-three. She had six things on the conveyor belt: a loaf of wheat bread, two cans of soup, bananas, coffee, and the little box of peppermint tea she bought every Saturday. Her hands had been shaking more lately, and that afternoon she was having trouble finding her wallet inside her purse.

I turned around.

The woman behind us had a cart piled high with groceries and one hand wrapped around her phone. She looked to be in her forties, well dressed, impatient, and completely comfortable with everyone hearing her.

“You want to say that to her again while looking at me?” I asked.

Mom touched my wrist.

“Rachel. Leave it.”

That was my mother. Even embarrassed, she was worried about me causing a scene.

She pulled out a packet of tissues, then her glasses case, then finally her brown leather wallet. The woman behind us sighed again.

“Finally. Some of us don’t have all afternoon.”

A couple near the magazine rack looked over. A man farther back stared at the floor.

Mom gave the cashier an embarrassed smile.

“I’m sorry. My hands aren’t as quick as they used to be.”

The cashier didn’t answer.

She was staring at my mother.

Not at the wallet.

At her face.

Her name tag said LINDA.

She looked about fifty-five, with short brown hair and reading glasses hanging from a cord around her neck. A second earlier, she had been scanning groceries without much expression. Now one hand was frozen above the register.

“Ma’am, what’s your name?”

Mom looked up.

“Dorothy.”

Linda leaned closer.

“Your full name, please.”

“Dorothy Miller.”

Linda went pale.

Then she reached beneath the counter.

There was a click.

The conveyor belt stopped.

The register screen went dark.

The woman behind us threw up both hands.

“Are you serious?”

Linda picked up the store phone without looking at her.

“Mark. Register six. Now. Bring the old cardboard box from my office.”

She hung up.

The woman behind us pushed her cart forward.

“I’ve waited long enough. Ring me up first.”

Linda finally faced her.

“No.”

The woman blinked.

“Excuse me?”

“Register four is open. Use it.”

“I was here first.”

Linda’s face stayed calm.

“And you just told an eighty-three-year-old woman she wasn’t worth waiting for. You can wait somewhere else.”

The Box Behind Register Six

I thought there had been a problem with Mom’s card.

Mom apparently thought the same thing because she opened her wallet and checked inside.

“Did something happen with my account?”

Linda shook her head.

“This has nothing to do with your money.”

“Then what is it?” I asked.

Linda kept looking at Mom.

“I’m trying to find out if I’ve been searching for the right woman.”

The woman behind us muttered that she wanted a manager.

“He’s already coming,” Linda said. “Just not for you.”

A manager appeared less than a minute later carrying an old cardboard file box with a loose lid. It looked strange in the middle of a grocery store, surrounded by gum displays and candy bars.

Linda took it with both hands.

“Thanks, Mark.”

He studied her face.

“You okay?”

“Ask me again in five minutes.”

She set the box beside the register.

Mom gripped her wallet tighter.

“Do I know you?”

Linda looked at her for several seconds.

“No. But I think my mother knew you better than almost anyone.”

Mom’s expression changed.

“What was her name?”

Linda lifted the lid.

“Susan Parker.”

Mom’s wallet hit the floor.

Coins rolled beneath the register.

I bent down automatically, but Mom didn’t move. She was staring at Linda as if the grocery store had disappeared around her.

“Say that again.”

“Susan Parker. She was my mother.”

Mom reached for the counter.

“Your mother was Susan?”

“Yes.”

“Susan Parker?”

“Yes.”

Mom sat down hard on the little bench beside the checkout lane.

I had never heard the name.

Not once.

“Mom, who is Susan?”

She didn’t answer me.

Linda reached into the box and removed a faded photograph.

She turned it around.

The picture was old, with rounded corners and a crease running through the middle.

My mother was in it.

She was much younger, maybe in her early thirties, standing in front of a small white house. Beside her was a skinny girl with dark hair, missing one front tooth.

Mom touched the photograph with one trembling finger.

“That’s my Susan.”

I looked at her.

“Your Susan?”

Mom swallowed.

“My sister died when Susan was six.”

She looked at Linda.

“I raised your mother.”

The Girl My Mother Lost

My aunt had died when Susan was six.

I knew Mom had once had an older sister, but she had died long before I was born. What I never knew was that her daughter had come to live with my mother afterward.

Mom raised Susan for almost six years.

She packed her lunches. Took her to school. Sat beside her when she had the flu. Made Halloween costumes at the kitchen table. Susan called her Aunt Dorothy, but according to Mom, they lived more like mother and daughter.

“She had a blue bedroom,” Mom said. “The ugliest blue you’ve ever seen. She loved it.”

Linda laughed through tears.

“She told me about that room until I could picture it.”

Mom looked up sharply.

“She remembered it?”

“She remembered you.”

Mom stopped smiling.

I was born when Mom was thirty-four. By then, she and my father were struggling financially. Dad had been laid off for several months, Mom was working part-time, and they were trying to prepare for a baby while supporting Susan.

One night, Susan overheard them talking in the kitchen.

Mom remembered the conversation almost word for word.

“I told your father, ‘I don’t know how we’re going to manage with both children.’ I meant money. Bills. Two kids. That was it.”

Linda lowered her eyes.

“That isn’t what a twelve-year-old heard.”
