Striving

bungling, that jump inelastic;
A shiver 'mongst the cherry branches,
grasping, those two furry fingers;
A tiny cloud of disturbed snow on the ground,
swooping, the graceless arc of that striped tail;
The shrunken cherry being reached trembles,
holding on, its grasp of the twig steadfast;
The shaken squirrel peeps up at its quarry,
Unfulfilled longings in desolate winters,
why all this
Striving?
