Father built model towers until the day he died.

He’d glue thin sticks together, like chopsticks, building the thing up a little at a time. That was all there was to it. But past a certain height, the tower always leaned, slow and sure, toward one side or the other. Then it toppled.

“Fell again.”

Whenever Mother brought in the tea, she’d find him grinning at the scattered sticks.

“So close, though.”

“You’ve been ‘so close’ for thirty years now.”

Mother would shake her head, set down the teacup, and leave him to it. Every night, the same ritual.

When Father died, only the half-fallen tower remained in the corner of the room.

Their son works on a space station. After the funeral, he carefully boxed up the tower and said he’d take it up with him.

“What are you going to do with that thing up there?”

“No idea. But if it stays here, you’ll just stare at it and cry every day.”

She had no answer for that.

A week later, a photo arrived from her son.

Mother stared at the screen and, for a moment, forgot to breathe.

The tower was standing.

Not a single stick had been added. The same half-fallen tower now stood with no lean at all — straight and true, without so much as a finger’s width of tilt.

“Up here, there’s no up or down,” her son’s voice came through, a beat behind the image. “Without weight, nothing leans under its own mass. Dad’s tower — we could build it as high as we want up here.”

Mother set down the teacup she’d been holding.

There was a line Father used to say.

— Someday I’ll take it somewhere it can really stand.

All these years, she’d assumed he meant a shelf to display it on once it was finished. She’d been wrong. He’d been searching for the place where it could finish standing at all, a place that had never existed down here on the ground.

The following spring, for the first time in her life, Mother sat in a launch seat.

Her wrinkled hands fumbled the unfamiliar buckle until it clicked shut. The attendant beside her leaned in. “Aren’t you scared?”

“A little. But my husband spent thirty years building something worth seeing, and it’s waiting up there.”

She straightened her back and looked straight ahead.
