You will see a nice empty space beside this pot with the small shrub in it. The space, or gap, is a kind of ‘Now What?’ area. A possibility, or a bit of waiting-to-happen room (rather than a waiting-room, which is often such a deadly space).
I’ve heard some people talk about the influential value of rests in music. Sometimes a gap can be a powerful thing, alive with the fascination of what’s possible (pace Yeats). Maybe it’s the place where our imaginations live.
