Kendra nodded and walked toward her bus.

Nothing about the conversation was openly insulting. Still, two days later Kendra learned Sadie had joked to a friend that the Community Action Committee had chosen the only senior without a car to help organize a car wash.

The friend replied, “Her dad literally works for a construction company and her mom works at a clinic. What are you talking about?”

Sadie answered, “I was joking.”

The joke reached Kendra through Emily.

For the first time, Kendra wrote something down.

Oct. 14 — Sadie jokes about me not having a car + car wash.

She did not know what she would do with the note. She simply wanted to stop wondering whether memories were becoming more dramatic after the fact.

A second line followed three days later.

Brookstone’s newspaper published an editorial about inconsistent enforcement of the school dress code. Kendra had helped edit the piece but did not write it. The editorial noted that Black girls wearing head wraps and bonnets had received comments from staff while white students wore baseball caps and athletic headbands without similar scrutiny.

Sadie saw Kendra near the cafeteria and said, “So now the paper is doing race investigations?”

Kendra told her the editorial board approved the piece.

“But you edited it.”

“Yes.”

“So you agree.”

“That is generally how editorial boards work.”

Sadie laughed. “You really do love this stuff.”

“What stuff?”

“Finding discrimination everywhere.”

Kendra’s expression changed. “I didn’t write the incidents.”

“You know what I mean.”

“No.”

Sadie looked irritated. “I’m not having this conversation.”

“You started it.”

Sadie walked away.

Kendra added another line to the note.

The first event she formally reported occurred in November. Brookstone held a lunchtime fundraiser selling school-branded sweatshirts and hats to support a local housing nonprofit. Sadie managed the cash table.

Kendra bought a hoodie for Cameron, her fifteen-year-old brother, using a fifty-dollar bill Wesley had given her that morning. Sadie accepted it, held it toward the light, rubbed the paper between her fingers, and then used a counterfeit marker.

Kendra watched.

“Is something wrong?”

“No.”

“Then why are you checking it?”

“We check larger bills.”

Kendra looked toward the cash box. Five minutes earlier, she had watched Sadie accept a hundred-dollar bill from white senior Trevor Mills without checking it.

“You didn’t check Trevor’s.”

Sadie’s expression tightened. “I know Trevor.”

“You know me.”
