My 5-year-old son suddenly pointed at a stranger in the bakery and said he knew her. Then I noticed the necklace around her neck—and froze.

I would have walked straight past her if my son hadn’t grabbed my sleeve.

It was Tuesday afternoon, and after a long shift at the hospital, all I wanted was to buy groceries, take Toby home and order something easy for dinner.

My five-year-old was sitting in the shopping cart, quietly talking to himself while I checked items off my list.

Then he suddenly stopped.

“Mommy?”

Something in his voice made me turn.

Toby was staring toward the bakery.

A young woman stood beside the display case, waiting for an employee to box a cake.

Toby pointed at her.

“I know her.”

I barely looked up.

“From preschool?”

He shook his head.

“No. She comes to our house.”

My hand stopped over the cart.

“What do you mean?”

He leaned closer, as though he were telling me a secret.

“She comes when you’re working.”

For a moment, I couldn’t process the sentence.

Then he added something that made my stomach tighten.

“She goes into your bedroom.”

I stared at him.

“Toby, are you sure?”

He nodded with the absolute confidence only a five-year-old can have.

“Daddy knows her.”

My eyes moved toward the woman.

Ten years of marriage flashed through my mind.
