Harry's laugh shatters the quiet breakfast.

"OH!" starts Harry. "I get it!"

"Get what?" asks Ginny.

"The Mirror of Erised!"

Ginny eyes her husband curiously. "…okay?"

"Erised," explains Harry, grinning wildly. "Erised!"

"What? That it's 'desire' spelled backwards?"

Harry gasps. "You knew?"

"Ron told me in his owl right after the Quirrell thing."

"Ron knew?"

"Sweetheart," Ginny sighs, "everyone knew. It's not that hard. James figured it out the first time I told him the story. He was six."

"Oh."

"It really took you a quarter century to catch on?"

"…maybe."

Ginny chuckles. "Finish your toast, dear."
