She was the little girl who had wanted a purple house. Her hair was in two braids that had not survived the day neatly, and she still had the solemn focus children carry when they take dreams personally.

She held up the spare key I had given her months earlier. She had looped it onto a blue ribbon and worn the ribbon around her neck.

“I didn’t lose it,” she said before even saying hello.

“I can see that.”

“I look at it before school.”

“That seems like a lot of pressure for a key.”

“It helps me remember.”

“Remember what?”

“That I can build my house.”

Her mother smiled the tired, proud smile of someone who had been hearing about this key at breakfast for months.

Lily looked past me toward the porch where the older kids were packing up laptops. “Can I come to computer Saturdays when I’m old enough?”

“You are old enough to ask good questions,” I said. “That’s usually the more important qualification.”

She smiled so hard her whole face changed.
