As I took the escalator down into the Embarcadero BART/Muni station, a really large sycamore leaf bumping around at the top of the escalator indicated that everything is going to be okay.

Okay meaning, in this case, quite good, in proportion to the outstanding, almost silly, size of the leaf.

The large leaf had fallen from one of the several non-large sycamore trees that had been transplanted fairly recently into a sidewalk grouping.

A leaf like that has occasion to know.

It has until recently been directly connected with the earth. It doesn't read newspapers, and so has perspective. It's been doing nature life in a very human-built area.

If the leaf is fairly optimistic in the midst of brick/concrete/stone, I can only let its informed optimism fall in my insides and compost me richer.
