Principle above sap

That’s how it was. It was like we had had something in Jefferson for eighteen years and whether it has been right or whether it had been wrong to begin with didn’t matter anymore now because it was ours, we had lived with it and now it didn’t even show a scar, like the nail driven into the tree years ago that violated and outraged and anguished that tree. Except that the tree hasn’t got much choice either: either to put principle above sap and refuse the outrage and next year’s sap both, or accept the outrage and the sap for the privilege of going on being a tree as long as it can, until in time the nail disappears. It dont go away; it just stops being so glaring in sight, barked over; there is a lump, a bump of course, but after a while the other trees forgive that and everything else accepts that tree and that bump too until one day the saw or the axe goes into it and hits that old nail.
