아람, aram: a chestnut or an acorn ripe enough to fall by itself. Also the nut, once it has.
Nobody pulled it down. It took a whole summer of sun and rain at its own rate, and at some point the join to the branch goes slack.
A burr has three seams. It opens on the sunny side first and splits from there, the way a mouth opens. Some drop the nut and stay up in the tree; some come down still shut, burr and all. You can tell which by the sound they make landing.
The ones twisted off early taste different. One is enough to know.
Under the tree this week the ground is covered in split burrs, every one of them opened from the inside.
