The realtor's key stuck in the lock again.

Sarah rearranged Olivia on her hip as the woman jiggled the stubborn mechanism. In the background, Lucas stood backlit by the afternoon sunlight, his shadow casting long over the overgrown lawn of the little yellow house.

"Nearly. got it!" The realtor made a final twist, and the door creaked open with a whiff of dust.

Olivia sneezed into Sarah's shoulder. "Dirty," she proclaimed, scrunching up her nose.

Sarah stepped across the foyer into the empty living room, her prints tracing the hardwood. Sunbeams streamed in the grimy windows, illuminating whirling dust motes. The smell of lemon polish and decades filled the air—someone else's memories trapped in the walls.

Lucas's footsteps echoing as he strode across the room, his architect's eye noticing the buckled floorboards, the water stain in the ceiling, the way that the front window positioned the giant oak in the yard exactly where it was.

Sarah tracked his face as he turned slowly round—the set of his eyes on the built-in bookshelves to either side of the fireplace, the slight curve of his lips as he pictured their life here.

Olivia squirmed to be put down, at once making a dash for the stairs. "My room upstairs?"

Sarah caught her hand before she reached the first step. "Maybe, baby. Let's have a look."

They strolled through the house as though venturing into new country—the kitchen with its worn but charming farmhouse sink, the sunroom that would be perfect for Sarah's paint and brushes, the back yard where fireflies would spark on balmy nights.

In the master bedroom, Lucas pressed his palm against the wall. "This is the one," he breathed.

Sarah moved over to stand alongside him, shoulders touching. She saw it all of a sudden—their bed here against this wall, morning sun coming through those curtains, the quiet intimacy of shared space.

Olivia tugged on her sleeve. "Hey, look! Fairy door!" She indicated a tiny mouse hole near the baseboard.

Lucas got down on his knees, totally serious as if he's reviewing blueprints. "You're right. We'll have to leave them cookies."

Sarah's throat tightened suddenly. This was not a house. It was a set where their daughter would reside, where they'd have holidays and weather storms, where they'd build a life brick by brick, memory by memory.

The realtor looked at her watch outside. "I'll give you a moment to talk."

They sat on the porch steps up front—the three of them sitting together in a row—while the oak's shadow lengthened toward them. Olivia leaned against Lucas, tired in the heat of the afternoon.

Sarah peeled a corner of the paint that was peeling off the step. "It needs repair."

Lucas nudged her shoulder. "So did we."

The reality of the situation was negotiated between them. They were not the same people that had fallen in love all those years ago—shameless and battered and believing they could fix each other. They were more real than that now, more solid which had survived storms and come out stronger.

Sarah turned her face into the breeze, imagining the creak of these stairs underfoot as she carried out holiday decorating decades from now. The squeak of a teenager's chair at the breakfast table. The way Lucas would grumble about raking leaves yet always leave one on the ground to jump in.

She squeezed his hand, wedding bands glinting in the sunlight. "Let's go home."

Lucas's hands gripped hers harder. They understood perfectly what she was saying—not back to the apartment with the thin walls and cramped rooms, but forward. Into this imperfect, beautiful future that they would build.

Olivia's head dropped into the crook of Lucas's arm as he came to his feet, lifting her effortlessly. Sarah stood, too, to touch the hard bark of the oak tree—a promise in quiet to the house and to one another.

They would laugh and cover these walls. Love and fill these rooms. Plant roots as deep as the ancient tree's and grow toward the sun as one.

The realtor looked up hopefully as they came up. Sarah smiled and said the words that would change everything:

"We'll take it."
