He asked before moving furniture.

He stopped calling her treatment schedule an inconvenience and started putting the appointments on a shared calendar.

On days when he couldn’t drive her, he told us early instead of waiting for someone else to solve the problem.

It was progress.

It did not erase what happened.

When I told him that, he said, “I know.”

And for once, I believed he understood the difference.
