Readiness is less romantic than it sounds. It looks like a Saturday that is not already spoken for, a phone you can answer without dread, an ending that was properly finished rather than left ajar.
People talk about being open as though it were a feeling. Mostly it is capacity — actual room in a week, actual tolerance for the awkwardness of a first hour with a stranger.
When it happens, the timing will look like luck. Some of it will be. The rest will be that you had cleared the space where it could sit down.
